Abstract:

Magnesium oxide nanoparticles were deposited by laser pyrolysis process. Three types of lasers were employed CW CO2, Q-switched Nd-YAG (short pulses) and long pulses Nd-YAG lasers. The size and density of nanoparticles vary with laser energy, power, pulse duration and the scanning speed of the laser. In this method, MgO nanoparticles were deposited by a laser beam on a quartz substrate from aqueous solution of magnesium nitrate. AFM images reveal formation of small nanoparticle size of 24.5 nm with surface roughness 6.97nm by Q-switched Nd-YAG laser (10 ns) when the energy was 1J. While for CO2 laser, the smallest size was 18.8 nm at 0.4mm/s scanning speed with surface roughness 5.21nm at the same scanning speed. Moreover, long Nd-YAG pulses laser produces relatively larger average size of 37.5nm at 0.8ms pulse duration. The absorption spectra from UV-Visible spectroscopy were also conducted. The best absorption intensity was obtained at a wavelength ranging between 420-430 nm for both lasers. Finally, Thermal analysis using COMSOL Multiphysics software for the deposition process reveals that maximum temperature about 440Kfor Q-Switched Nd-YAG laser at 1J laser energy. While for RF CO2 laser, the maximum temperature obtained at 0.4mm/s scanning speed is 850K.This work provides a good knowledge for the deposition of nanoparticles using laser beams.

Abstract:

The main objective of this review is to verify the validity of laser therapy in the treatment of dentin hypersensitivity, an extremely common problem in patients, with Nd: YAG lasers or high- and/or low-power diode lasers to obtain a definitive protocol for the treatment of hypersensitivity, given the multiplicity of laser treatments proposed by the numerous authors evaluated. The authors performed an electronic search on PubMed, favouring it as a search engine. Lasers represent a means of treating dentin hypersensitivity, used alone and/or in conjunction with specific products for the treatment of such a pathology. The selected articles that examined diode lasers were divided according to the wattage (w) used: low-level laser therapy protocols, i.e., those using a wattage of less than 1 W, and high-level laser therapy protocols, i.e., those using a wattage of 1 W or more. Regarding the Nd: YAG laser, it was not necessary to subdivide the studies in this way, as they used a wattage of 1 W or more. A total of 21 articles were included in the final selection. Laser therapy was found to be effective in the treatment of dentin hypersensitivity. However, the level of effectiveness depends on the laser used. The results obtained from this review show that both the Nd: YAG laser and the diode laser (high and low power) are effective in the treatment of dentin hypersensitivity. However, the high-power laser appears to be more effective in combination with fluoride varnish and the Nd: YAG laser achieved greater long-term benefits than the diode laser.

Abstract:

Becker’s nevus (BN) is a cutaneous hamartoma of benign nature that develops through adolescence and affects mostly young men. The nevus is usually located unilaterally and is characterized by hypertrichosis and hyperpigmentation. Despite recent advances in treatment modalities, no effective treatment has been established for BN hyperpigmentation. We sought to assess the efficacy and safety of fractional Erbium: YAG 2940 nm and Q-switched Nd: YAG 1064 nm lasers in the treatment of BN hyperpigmentation. Twenty-three patients with BN were included in a prospective, randomized-controlled, observer-blinded, split-lesion comparative technique trial. In each patient, two similar square test regions were randomized to either be treated with a fractional Erbium: YAG 2940 nm laser or with a Q-switched Nd: YAG 1064 nm laser. Each patient was treated with three sessions at six-week intervals. At the follow-up, clearance of hyperpigmentation was assessed by physician global assessment, visual analogue scale, grade of improvement, patient global assessment, and patient satisfaction. Regions treated with the fractional Erbium: YAG 2940 nm laser demonstrated significantly better improvement compared to ones treated with the Q-switched Nd: YAG 1064 nm (p-value = 0.001) laser. Adverse effects such as repigmentation and hypertrophic scarring were not reported during the follow-up period. The outcomes were cosmetically acceptable with overall high satisfaction among the included patients. Our data suggest a superior role for the fractional Erbium: YAG (2940 nm) laser in the treatment of BN hyperpigmentation compared to the Q-switched Nd: YAG (1064 nm) laser, along with being a safer method and having no reported side effects.

Abstract:

In this work, we have presented a finite element (FE) numerical modelling simulations to study and analyze the thermal effects in Nd : YAG and composite YAG/Nd : YAG laser rods. We have calculated the temperature distributions, stress intensity and thermal focal lengths at different pump powers for both rods. The FE simulations showed that using composite laser rod of undoped cap reduces the maximum value of stress intensity and thermal focal length by ~35% and ~ 50%, respectively. We have verified the FE calculations experimentally by direct measurement of focal length of thermally induced lens by using Hartmann-Shack wavefront sensor. Good agreement was obtained between FE calculations and experimental measurements. Keywords: Nd : YAG lasers, Thermal lens, Wavefront sensing, solid state lasers.

Due to the increasing use of laser technologies in oncourology,we consider it relevant to publish a review of domesticand foreign articles for 2015-2021. The range of application ofvarious lasers in oncourology is very wide (holmium (Ho): YAG,thulium (Tm): YAG, etc.). In comparison with traditional surgicalinterventions, the greatest effectiveness of laser technologies incombination with endoscopy is clearly traced, the risks of intra –and postoperative complications are minimized, the period ofinpatient stay for patients changes.

Abstract:

La parodontite chronique est une maladie inflammatoire d'origine bactérienne. Elle se traduit par la perte d'attache et l'apparition d'hypersensibilités dentinaires, après exposition du cément radiculaire suite aux récessions gingivales. La prise en charge de cette pathologie repose sur une thérapeutique étiologique mécanique, qui est réalisée avec des inserts ultrasoniques ou des curettes manuelles. Depuis quelques années, le laser Er :YAG a été introduit comme alternative pour le traitement des parodontites chroniques, aussi bien au niveau du débridement radiculaire que pour le traitement de l'hypersensibilité dentinaire. Dans ce travail, nous avons voulu dans un premier temps, comparer le débridement laser au traitement mécanique conventionnel. Une étude clinique pilote a été menée dans le cadre d'un protocole de recherche clinique. Les résultats de cette étude montrent que le débridement au laser Er :YAG donne des résultats cliniques au moins similaires au surfaçage radiculaire manuel avec une supériorité en termes de gain d'attache clinique. Dans un second temps, nous avons voulu explorer l'action du laser Er :YAG sur l'hypersensibilité dentinaire. Une étude menée in vitro pour observer l'effet microscopique de ce laser sur les tubuli dentinaires exposés, a permis d'observer l'oblitération de ces derniers. Un cas clinique d'hypersensibilité traité par le laser a permis de confirmer ces résultats. Dans la limite des résultats de ce travail, nous pouvons conclure que le laser Er :YAG pourrait être une alternative intéressante dans le cadre de la prise en charge des parodontites chroniques
Chronic periodontitis is an inflammatory disease with an infectious bacterial etiology. One of its clinical manifestations is dentinal hypersensitivity after root cementum exposure. Its clinical management consists of implementing proper oral hygiene, then performing a mechanical cause-related therapy. The latter is realized using ultrasonic devices or manual curettes. Er:YAG laser debridement was introduced as a therapeutic tool for periodontal root debridement. We wanted to compare the latter to conventional mechanical scaling and root planning, in terms of clinical parameters. A pilot clinical study was carried at the CHU of Nantes. We found that both therapies lead to significant improvements of clinical periodontal parameters. No significant superiority between both modalities was found, except for clinical attachment level. On the other hand, Er:YAG laser was found to be capable of treating dentinal hypersensitivity. An in vitro study permitted te observe the microscopical obliteration of dentinal tubules after laser irradiation. A clinical case of dentinal hypersensitivity was also managed using the Er:YAG laser. Within the limit of the study, Er:YAG laser debridement could be an alternative to conventional mechanical therapy

Abstract:

Introduction: For approximately the last eight years the Laser Section of the National Physical Research Laboratory (NPRL) has been interested in inter alia, pulsed solid-state lasers and in particular, Nd:YAG. Investigations of various resonator types were undertaken with a view to the improvement of the laser parameters such as output energy, pulse width, beam quality and sensitivity to mirror misalignment. In 1980 a Nd: YAG laser employing a rotating prism Q-switch was constructed (Preussler (1980)). It involves rotating one of the two cavity reflectors so that they are parallel for only a brief instant in time. Typically the prism must rotate at a speed of 20 000 r.p.m. to ensure a single pulse output. Such lasers suffer from the tendency to emit multiple pulses, they are very noisy and they require frequent maintenance because of the short lifetime of the bearings. A resonator employing conventional curved mirrors and an electro-optical Q-switch was constructed in 1980 (Robertson & Preussler (1982)). In 1981 an electro-optically Q-swi tched laser making use of a crossed Porro-prism resonator was investigated due to its relative insensitivity to misalignment of the reflectors compared with the conventional mirror resonator (Nortier (1981)). Improvements in terms of output power, beam divergence and beam quality can be achieved by making use of a so-called unstable resonator. Such a laser has been investigated and is reported on in this study. Chapter 2 provides some background into laser theory and operation while chapter 3 deals with the theory of the unstable resonator. Chapter 4 provides details of the experimental equipment and techniques used in the work and chapter 5 discusses the evaluation of the project and results obtained.

Abstract:

Includes bibliographical references (leaves 151-163). Investigates the behaviour of the intensity noise in a multimode Nd:YAG laser. The collective modes of oscillation are excited by broadband ambient noise. Because the phase of the excitation is unknown, a cross spectral technique to measure the antiphase dynamics directly and form a picture of the intensity noise interference for two to five mode operation is developed. For three mode operation, the contributions of the longitudinal modes to collective modes is measured.

Abstract:

Objetivo: O Holmium:YAG laser é o método de litotripsia intracorpórea para cálculos urinários mais recentemente introduzido em nosso meio. O objetivo deste estudo é analisar a eficácia e as complicações imediatas do tratamento de pacientes com cálculos ureterais com essa fonte de energia. Casuística e Métodos: Foram tratados 16 pacientes, nove homens e sete mulheres, portadores de cálculos ureterais sintomáticos, maiores ou iguais a 6 mm, ou com evolução superior a 30 dias. A média de idade foi 42 anos (6- 68 anos). Quatro cálculos estavam localizados no ureter superior, seis no ureter médio e seis no ureter inferior. A técnica empregada foi a de vaporização do cálculo com Holmium:YAG laser, através de ureteroscopia. Utilizou-se exclusivamente ureteroscópio semi-rígido de 7 Fr. Resultados: A taxa de sucesso obtida foi de 87,5%, sem diferença estatisticamente significativa em relação ao relatado na literatura. Todos os cálculos foram fragmentados. Os dois insucessos da série ocorreram com cálculos localizados em ureter superior, em que fragmentos foram deslocados para o rim. As complicações observadas foram três perfurações ureterais e dois casos de febre. Conclusão: O Holmium:YAG laser é eficaz no tratamento endoscópico do cálculo ureteral. Medidas destinadas a prevenir a migração retrógrada do cálculo ou de seus fragmentos devem ser tomadas, principalmente no tratamento dos cálculos localizados em ureter superior. A litotripsia com Holmium:YAG laser não é, entretanto, um método isento de complicações, particularmente no que se refere ao tratamento de cálculos impactados de ureter superior.
Objetive: Holmium:YAG laser is the more recently method of intracorporeal lithotripsy of urinary calculi introduced in our area. The purpose of this study is to analyze the technique and to evaluate the immediate results and complications in the treatment of patients with ureteral calculi. Casuistry and Methods: Sixteen patients were treated, nine men and seven women, carrying symptomatic ureteral stones, bigger than 6 mm or with evolution superior to 30 days. The average age was 42 years old (6-88 years old). Four stones were localized in upper ureter, six in middle ureter, and six in lower ureter. The technique employed was the vaporization of the stone with Holmium:YAG laser, through ureteroscopy. It was used exclusively 7-Fr semirigid ureteroscope. Results: The rate of success attained was of 87.5%, with no statistically significant differences regarding the reports in literature. All the stones were fragmented. The two failures of the series occurred with stones localized in upper ureter, in which fragments were displaced to kidney. The complications observed were three ureteral perforations and two fever cases. Conclusion: Holmium:YAG laser is effective in the endoscopic treatment of ureteral stones. Measures aimed at preventing retrograde migration of stones or fragments should be taken, mainly when the stone are located in the upper ureter. However, lithotripsy with Holmium:YAG laser may be associated with complications, particularly in what concerns the treatment of impacted stones.

Abstract:

No tratamento endodôntico, várias fases de igual importância são necessárias para a realização de uma terapêutica bem sucedida, entre elas podemos citar a instrumentação. Apesar de todas as técnicas e instrumentos propostos para a Endodontia, o sucesso esperado ainda não foi alcançado. Tanto a instrumentação manual quanto à rotatória não resulta na limpeza das áreas polares dos canais radiculares com achatamento mésio-distal. No intuito de obter melhor resultado clínico, avaliou-se in vitro a remoção da camada de smear das paredes dos canais radiculares de 40 dentes incisivos inferiores portadores de achatamento mésio-distal submetidos à instrumentação rotatória por meio da técnica Free Tip Preparation, utilizando o laser de Er: YAG nos parâmetros de 140 e 250 mJ. Para tanto, a fibra óptica do aparelho foi deslocada lentamente, com velocidade de 2 mm/s, até o orifício cervical na câmara pulpar, na parede vestibular e lingual da raiz; e sua eficácia na remoção da smear foi comparada aos grupos onde se utilizou apenas Hipoclorito a 2,5% e Hipoclorito de sódio a 2,5% alternado com EDTA a 17%. Os dentes foram analisados por meio de microscopia eletrônica de varredura, e as fotomicrografias das áreas mais representativas dos terços médio e apical foram avaliadas por três examinadores diferentes, com grau mínimo de Mestre, que observaram a quantidade da camada de smear presente nas amostras em relação a três padrões. Os examinadores, sem que tivessem o conhecimento prévio de qual dos grupos estavam avaliando, atribuíram escores de 1 a 4 as fotomicrografias, de acordo com a quantidade da camada de smear visualizada. Os dados obtidos foram submetidos à análise estatística não-paramétrica, comparando-se os diferentes grupos estudados (teste de Kruskal-Wallis) e os terços radiculares (teste de Wilcoxcon). Os resultados mostraram que, quanto à quantidade da smear encontrada nos grupos estudados, o grupo que utilizou Hipoclorito a 2,5% alternado com EDTA apresentou os canais radiculares mais limpos seguido do grupo do laser 250 mJ e posteriormente pelos grupos do laser Er: YAG a 140 mJ e do hipoclorito a 2,5%, que não apresentaram diferença estatisticamente significante entre si. Quanto aos terços, o apical apresentou maior quantidade da smear em comparação com o terço médio (p< 0,01).
Manual or rotary instrumentation techniques do not efficiently clean mesio-distal flattened root canals. This study evaluated, in vitro, smear layer removal of 40 mesio-distal flattened root canals after rotary instrumentation. The teeth were then divided into 4 groups: group 1: rotary instrumentation and 2.5% sodium hypochlorite used as irrigating solution; group 2: instrumented as group 1 and followed by Er: YAG laser irradiation (140mJ input/10Hz), withdrawn at 2mm/s from the apical to the cervical region touching the buccal walls the procedure was then repeated for the lingual wall); group 3: instrumented as group 1 and followed by Er: YAG laser irradiation (250mJinput/10Hz) withdrawn at 2mm/s from the apical to the cervical region touching the buccal walls the procedure was then repeated for the lingual wall) and group 4: instrumented as group 1 and alternated with 17% EDTA Teeth were split longitudinally and prepared for examination under scanning electron microscopy. Scores from 1 to 4 were given to the fotomicrographs by three independent evaluators, and these data was submitted to statistical analysis. The teeth where alternated 17% EDTA were used (group 4) showed less amount of smear layer, followed by the group irradiated with 250mJinput/10Hz (group 3), the group irradiated with 140mJ input/10Hz and the group where only sodium hypochlorite was used. The apical third presented more smear layer than the middle third (p<00.1).

Abstract:

Au cours de cette thèse, nous nous intéressons à deux applications nécessitant des sources laser impulsionnelles : l'imagerie active et l'usinage laser. L'imagerie active nécessite des sources laser efficaces émettant dans la gamme de sécurité oculaire (entre 1,5 µm et 1,7 µm) à des cadence de l'ordre du kilohertz et produisant des énergies par impulsion de plusieurs millijoules. Les sources efficaces émettant dans la gamme de sécurité oculaire utilisent l'ion erbium. Cependant la structure électronique complexe de l'ion erbium entraîne de nombreux effets parasites qui limitent fortement l'énergie accessible lors d'un fonctionnement à haute cadence. Pour diminuer l'influence de ces effets parasites nous avons utilisé le concept de fibres cristallines dans le cadre d'une collaboration entre le Laboratoire Charles Fabry et l'entreprise Fibercryst. La géométrie des fibres cristallines, combinant les propriétés des cristaux massifs et les avantages des fibres en verre nous a permis de dépasser les limites des sources actuelles. L'usinage de matériaux requière des sources laser impulsionnelles émettant dans le proche infrarouge (1 µm) et alliant forte énergie, forte puissance crête et forte puissance moyenne. Pour réaliser de telles sources, il est nécessaire d'utiliser des milieux à gain permettant de limiter les phénomènes thermiques et les effets induit par la puissance crête (effets non-linéaires). Pour cela nous avons utilisé à nouveau le concept de fibre cristalline, dopée cette fois ci par l'ion néodyme. Ces fibres cristallines ont été utilisées comme amplificateur de puissance pour amplifier des micro-lasers fonctionnant à haute cadence (de 1 à 100 kHz) et produisant des impulsions courtes (< 1 ns).

Abstract:

Recent advances in mode-locked solid-state lasers have resulted in pulses as short as 8.5 fs in the 800 nm region from Ti:sapphire oscillators [1]. Using similar techniques, sub-50 fs pulses [2-4] have been generated in another solid-state laser system, Cr:forsterite, which operates in the 1.2 to 1.3 μm range. We report here results from both a regeneratively-initiated and self-initiated, mode-locked Cr:YAG laser [5] which is tunable from 1.51 to 1.53 μm. One hundred and twenty femtsosecond, nearly transform-limited pulses have been generated with peak output powers of 45 kW. The stable, high peak power pulses and room temperature operation of this laser make it a very suitable alternative to the cumbersome, cryogenic mode-locked NaCl laser [6] commonly used in both narrow bandgap semiconductor and optical communications research.

Abstract:

Cr-doped garnets such as YSAG and YSGG emit broadband Cr fluorescence in the near-infrared spectral region. Due to a resonant dipole-dipole interaction between Cr3+ and rare earth ions like Nd3+, Tm3+, and Ho3+, efficient nonradiative transfer can be achieved in such Cr-sensitized systems. Even Cr3+ in YAG with a rather narrowband emission at a strong crystal field site can be used to sensitize especially Tm3+ because of the overlap between the Cr emission and Tm absorption in YAG.
