R. Martinezherrero et al., BEAM-QUALITY CHANGES GENERATED BY THERMALLY-INDUCED SPHERICAL-ABERRATION IN LASER CAVITIES, IEEE journal of quantum electronics, 31(12), 1995, pp. 2173-2176
Thermally-induced spherical aberration in Nd:YAG rods is investigated,
Attention is concentrated on the so-called ''intensity moment formali
sm'' to analyze the beam-quality parameter of the emitted laser beams,
A number of resonance conditions that certain beam-shape parameters o
f any stable laser mode should fulfill are also derived, and a compari
son with previously reported numerical results is presented.
