Full textLong term stabilised lasers are used in a multitude of metrological applications and are the basis of experimental research in very high resolution spectroscopy. This document describes my thesis work on stabilised Nd:YAG lasers in view of space applications (for fundamental physics experiments and geodesy). All experiments must satisfy criteria of compactness, mechanical stability, robustness and reliability. I will describe the possible references for the long (molecules) and the short (resonators) term time intervals with their principal limitations. The discussion leading to their choice is actually connected to the stabilisation techniques to be adequately implemented (PDH, Tilt-Locking, Modulation transfer). Among the stabilisation techniques, the Pound-Drever-Hall (PDH) technique is now a classic as it produces the best performance in short term, so far. To reduce active components, we have also implemented a DC technique called Tilt-Locking and I will compare with PDH in the case of a monolithic Fabry-Perot reference. Theoretical performances on the long term and quantum efficiencies will be compared for different techniques. The schematic principles of the experiences and the results I have obtained for stabilised lasers on Fabry-Perot and molecular iodine are presented. We calibrated the Fabry-Perot drifts, this allows me to point out analytical and numerical solutions to control the length of this mechanical reference. Finally suggestions for further work will be approached and, in the appendices, details about noise order of magnitudes for LISA, a theoretical overview of gravitational waves as well as different simulations and calculations are presented

Full textSUMMARY Disinfection of intracanal dentin by Nd:YAG, Ho:YAG and Er:YAG laser irradiation: an in vitro model A possible cause for root canal failure is the persistence of bacteria that have colonized dentinal tubules. To reduce this risk and, if possible, to also shorten the time-consuming endodontic therapy, new equipment and materials are constantly being introduced. The aim of the present investigation was to study the effect of disinfection of dentinal tubules by intracanal laser irradiation using an in vitro model. The groups irradiated by various lasers were compared with calcium hydroxide, a material frequently used as intracanal medication between appointments. Freshly extracted, intact bovine incisors were used. The root cementum was removed and the teeth cut to produce 180 standardized specimens. For bacterial colonization, specimens were incubated at 37 o C in test tubes with Tryptic Soy Broth and Enterococcus faecalis, which carried a plasmid that allowed the growth in a selective medium containing chloramphenicol. The specimens were divided in five treatment groups and three control groups. For irradiation, pulsed delivered Ho:YAG laser at 2.1 µm, Nd:YAG laser (1.06 µm), and Er:YAG and Er:YAG laser (2.94µm) with and without air/water coolant, were used. Lasers groups received three different laser settings for treatment: output energy below the physical modification threshold (½ of PMT) for 60 sec, at the PMT for 60 sec and above the PMT (120 sec). Group 5 received a seven-day treatment with calcium hydroxide. As controls, three specimens for each treatment group received sterile water instead of bacteria (negative control), three received iodine potassium-iodide after bacterial exposure (negative control), and three did not receive treatment after bacterial exposure (positive control). The number of bacteria was estimated by counting CFU. In order to evaluate whether the lasers used in the experiment could be absorbed by the bacteria E. faecalis, an UV, VIS and NIR spectra were obtained using a spectrophotometer. Statistical analysis showed the bacterial reduction as follow: Ho:YAG laser > hidróxido de cálcio> Nd:YAG laser > Er:YAG laser with air/water coolant > Er:YAG laser without air/water coolant. There was a significantly higher bacterial reduction in the group irradiated by the Ho:YAG at the PMT (50mJ, 10 Hz, 66 J/cm 2 for 120 sec), followed by Ho:YAG irradiated at 50mJ, 10 Hz, 33 J/cm 2 for 60 sec, and the group that received calcium hydroxide. The latter two groups were not significantly different. The UV and VIS absorbance spectrum presented two absorbance peaks at 361nm and 337nm (UV). The NIR spectrum revealed a very low absorbance by the E. faecalis.

Full textQuasi-three-level lasers in neodymium-doped crystals such asNd:YAG, Nd:YLF and Nd:YVO4have received a great deal of interest becausethey allow generation of blue light by frequency doubling. Forsolid-state blue laser sources, there exist numerousapplications as in high-density optical data storage, colourdisplays, submarine communication and biologicalapplications.
Efficient lasing on quasi-three-level transitions at 900-950nm in Nd-doped crystals is considerably more difficult toachieve than on the stronger four-level transitions at 1-1.1µm. The problems with these quasi-three-level transitionsare a significant reabsorption loss at room temperature and avery small stimulated emission cross section. This requires atight focusing of the pump light, which is achieved byend-pumping with high-intensity diode lasers.
n this thesis, progress in diode-pumped solid-state lasersfor generation of blue light by frequency doubling has beenmade. Nd:YAG lasers at the 946 nm transition have been builtand a maximum power of 7.0 W was obtained. By inserting a thinquartz etalon in the laser cavity, the938.5 nm laser linecould be selected. An output power of 3.9 W was obtained.
By using nonlinear crystals, frequency-doubling of laserlight at both 946 nm and 938.5 nm by second harmonic generation(SHG) was achieved. SHG of the 946 nm transition gives bluelight at 473 nm. Efficient generation of blue light has beenachieved in periodically poled KTP, both in single-passextra-cavity and intracavity configurations. More than 0.5 Wwas obtained at 473 nm by intracavity doubling. Intracavity SHGof the 938.5 nm transition gave slightly more than 200 mW at469 nm.
The influence of energy-transfer upconversion (ETU) is adetrimental effect in Nd-doped lasers. An analytical model hasbeen developed for continuous wave quasi-three-level lasersincluding the influence of ETU. The results of the generaloutput modelling are applied to a laser with Gaussian beams,and rigorous numerical calculations have been done to study theinfluence of ETU on threshold, output power, spatialdistribution of population-inversion density and fractionalthermal loading. The model is applied to a laser operating at946 nm in Nd:YAG, where thermal lensing and the dependency oflaser-beam size are investigated in particular. A simple modelfor the degradation of laser beam quality from a transversallyvarying saturated gain is also proposed, which is in very goodagreement with measurements of the laser in a plane-planecavity.
