Super-gaussian reflectivity unstable resonators of different magnification factor M have been applied to a high-gain, short-pulse XeCl laser, to investigate to what extent the output laser beam characteristics depend on M. It has been found that high magnification factors are required to get a fast establishement of a diffraction limited mode. However, as M is increased, the cavity feedback and then the super-gaussian mirror peak reflectivity should be also increased to get a good mode control of the laser oscillating radiation.

Abstract
Super-gaussian reflectivity unstable resonators of different magnification factor M have been applied to a high-gain, short-pulse XeCl laser, to investigate to what extent the output laser beam characteristics depend on M. It has been found that high magnification factors are required to get a fast establishement of a diffraction limited mode. However, as M is increased, the cavity feedback and then the super-gaussian mirror peak reflectivity should be also increased to get a good mode control of the laser oscillating radiation.File in questo prodotto:
