Paper Abstract

Phase aberrations play an important role in shaping the beam and in determining the losses of laser resonators. An efficient method is presented for modeling arbitrary phase aberrations in a resonator and for computing modes, modal losses and frequencies in the aberrated resonator. The method is then used to assess the effect of thermal phase aberrations in lasers where the active medium is a solid state rod, and in lasers where the active medium is an OPS (Optically Pumped semiconductor). The adverse effect of the thermal aberrations is found to be severe in the case of rod geometries and small and less significant in the case of OPS lasers. The analysis conducted allows one to identify simple design criteria that further minimize the effect of thermal aberrations in the case of OPS lasers.
