Full textNovel laser-active inorganic materials doped with thulium and holmium ions have been investigated for their potential in broadly tunable and ultrafast lasers operating in the short-wave infrared spectral range of 2 to 3 μm. Lasers emitting within this spectral range find numerous applications, including light detection and ranging systems, gas sensing, medicine. They are used as amplifying systems for high harmonic generation and terahertz generation, and further frequency conversion into the mid-infrared region.The present PhD thesis establishes relationships between the structural properties of oxide and fluoride crystalline materials, in the form of single crystals and transparent ceramics, and the spectroscopic properties of thulium and holmium dopant ions, along with their laser characteristics, which are essential for laser development. Moreover, the physical processes underlying unexpected laser behaviour are revealed. This systematic study of laser materials allows for the identification of the most promising compositions for the development of broadly tunable and ultrashort pulse lasers.This study mainly focuses on materials that exhibit significant inhomogeneous spectral line broadening, resulting in broad and structureless absorption and emission spectra of the dopant ions. In order to promote this effect, several strategies have been considered, including rare-earth ion clustering, local structure disorder, compositional disorder in solid-solution compounds, and phonon-sidebands arising from electron-phonon interactions.The formation of thulium and holmium clusters in calcium fluoride crystals enables efficient and broadly tunable laser operation around 2.1 μm. A polarized spectroscopic study of the emission properties of holmium ions in disordered calcium rare-earth aluminate crystals sheds light on its broadband spectral properties and on the role of multiphonon assisted emission, which occurs beyond electronic transitions, in unexpected laser emissions observed in mode-locked lasers. In solid-solution sesquioxide ceramics of the yttria-lutetia-scandia ternary system doped with thulium ions, there is a strong and nearly linear variation of the crystal-field strength with the mean size of the host-forming cation. This relationship allows for the customization of both the position and width of the emission band above 2 μm by appropriately adjusting the host composition. Highly efficient laser operations of thulium- and holmium-doped sesquioxides around 2.1 μm and 2.3 μm have been demonstrated

Full textThe conversion of light towards high frequencies is carried out according to three excitation mechanism types: successive absorptions of several photons, the excited-state energy transfer between ions and the photons avalanche. This last process is a collective effect based on an energy transfer between an excited ion and an unexcited ion. Under certain conditions, these transfers can lead to a chain reaction inducing an important increase of anti-Stokes fluorescent intensity. The object of this work is the systematic study of the anti-Stokes fluorescence of the trivalent rare earth ions in the fluorite crystals. The studies, which we present, are recorded by using a monochromatic excitation around 650 nm provided by a tunable dye laser. I have studied more particularly the erbium and thulium diluted ions in the KY3F10 single crystals. This study permits to determine Starks sub-levels of the various 2S+LJ multiplets of Er3+ and Tm3+ ions at liquid nitrogen temperature with a very good precision. We expose also the results relating to the dynamics of anti-Stokes fluorescence, by analyzing the variation of the fluorescence intensity as a function of the excitation power and by taking measurements of lifetimes. We also report the results of a spectroscopic study of anti-Stokes emissions from a Tm3+-doped KY3F10 crystal demonstrating the sensitized effect of Er3+ ions, present as trace impurities, on the excited-state absorption lines of Tm3. In addition to Er3+ ion, the Ho3+ ion does not increase the possibilities of resonant transfer with the Tm3+ ion

Full textOver the years a number of chalcogenide glass compositions have been studied as host matrices for Rare Earth (RE) ions. However, it still remains a great challenge to obtain a glass matrix with high solubility of RE ions and to fabricate a RE doped chalcogenide glass fiber with good optical quality. The present PhD thesis focuses on the study of new glassy systems as host matrices for doping of RE ions, which allowed to obtain RE doped optical fibers transparent in near and middle IR. Studied glassy systems were based on well-known arsenic sulphide (As2S3) glasses co-doped with Tm3+ ions and different glass modifiers. Firstly, the addition of Gallium (Ga) ions as co-dopants was examined and their influence on the emission properties of Tm ions was explored. With the incorporation of Ga into the host, Tm doped As2S3 glasses display three strong emission bands at 1.2 μm (1H5→3H6), 1.4 μm (3H4→3F4) and 1.8 μm (3F4→3H6) under excitation wavelengths of 698 nm and 800 nm. Despite the very small glass forming region of the system Ga-As-S we could optimise the concentration ratio of Ga and Tm to achieve the highest possible photoluminescence efficiency. From the optimal composition, Tm3+ doped Ga-As-S fiber was drawn and its luminescence properties were studied. Through structural characterisation of Tm doped Ga-As-S glasses, using Raman spectroscopy and Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy at As K-edge, Ga K-edge and Tm L3-edge, a formation mechanism has been proposed for this glassy system and it was correlated with luminescence features of Tm ions. In the second part, the modification of Tm3+ doped As2S3 glasses with the incorporation of halides (namely Iodine (I2)) was investigated, as a method for tailoring the process parameters for purification, in order to obtain a high purity glass matrix via chemical distillation. All three of above mentioned emission bands were observed for this system as well, under the 800 nm of excitation wavelength. Optical, thermal and structural properties of these glassy systems were characterized experimentally depending on the concentration of I2 and Tm in the glass, where the attention was concentrated on two principal aspects: the influence of the concentration of I2 on the intensity of emission of Tm and the mechanisms responsible for the increase of the solubility of Tm ions in As2S3 glass matrix with addition of I2.

Full textThis thesis relates to preliminary studies aiming to achieve quantum memories in rare earth ions doped inorganic crystals. If photons are the best vectors for information transport, materials systems represent the best quantum objects to achieve inforrmation storage and manipulation. As they are insensitive to decoherence by spontaneous emission, Raman transitions are an interesting process to realize the light-matter coupling. Rare earth ions have been chosen because they exhibit relatively long coherence lifetime. After a detailed presentation of the different rare earth ions and the different crystals, we justify the choice of working on Thulium:YAG ions, for which we built a stabilised laser. We discuss on the possibility to create an efficient three-level system in this material with the help of an external magnetic field, using the coupled effect of hyperfine interaction and electronic Zeeman interaction. We present the experimentals results of spectroscopy of Thulium ion in a magnetic field and we measure the system gyromagnetic factors, which present a good agreement with the theoretical values. We present the three-level system preparation procedure, aiming to eliminate the transitions inhomogeneous broadening. We describe a first coherent manipulation process of a thulium ions macroscopic ensemble: the population adiabatic transfer between two levels of the system, using the "Complex Hyperbolic Secant" excitation procedure. Transfer rates of about 95% have been achieved

Full textThis works presents studies of the production and the characterization of TeO2 -PbO-GeO2 doped with erbium, thulium and ytterbium ions and also prepared with different metallic nanoparticles for applications in displays. This glass system presents a broad transmission window in the visible and infrared (350 - 6500 nm), high solubility for rare earth ions, low phonon energy (about 700 cm-1) and considerable chemical, mechanical and thermal, stabilities which are important factors for the production of displays or devices used for illumination. This work can be divided in three parts, and starts with the study of the photoluminescence of teluritte glasses doped with erbium followed by the study of erbium and ytterbium codoped glasses. The second part presents the influence of metallic nanoparticles on the luminescence of samples codoped with erbium and ytterbium and, finally, in the third part, the study of samples doped with erbium, thulium and ytterbium with and without metallic nanoparticles. The incorporation of rare earth ions in the trivalent form was determined by means of optical absorption and emission measurements and, by using the transmission electron microscopy technique to the nucleation of metallic nanoparticles. Among the codoped samples, produced with different metallic nanoparticles, we remark the sample produced with silver nanoparticles that presented enhancement of erbium upconversion luminescence of approximately 50%. Samples doped with erbium, thulium and ytterbium showed possible applications for full color displays.
