Developpment of new technologies for display and videoprojection are nowadays subject of great interest. RGB (Red-Green-Blue) laser sources are a very promising solution. By miniaturization of such sources, which is a huge DEFI, many applications can be reached. This work can be placed between these two problems: realization of a RGB laser source with one unic material, in order to reduce production prices, and miniaturization of such a source, by developing integrable microsctructured waveguides. To reach this objective, fluorozirconates glasses derived from ZBLA compositions (Zr - Ba - La - Al), doped with Praseodymium are studied. Three interesting emission bands of Praseodymium occur in the visible range, at blue (478 nm), green (532 nm) and red (635 nm) wavelengths. Furthermore, Praseodymium can easily be directly pumped at 443 nm using a blue GaN laser diode. Channel waveguides can be obtained on glasses surface using ionic exchange F- >Cl-, which is a quite simple and flexible method. This study is divided in six main parts: synthesis and characterization of the material, realization of channel waveguides using ionic exchange, spectroscopic study of rare earth in a glassy matrix, optical amplification measurement and study of the laser behavior of the couple glassy matrix/rare earth.
