Abstract
We investigate the influence of thermally induced spherical aberrations on the fundamental mode of a rod solid-state laser. Results concerning the additional losses and beam quality degradation are presented and point out that for a large volume fundamental mode resonator, a spherical aberration greater than 0.5(lambda) dramatically deteriorates the laser performances. To control the resonator performances, we present a new phase control technique with an intracavity optically addressed liquid-crystal spatial light modulator. The presented Nd:YAG resonator is able to deliver beams with various spatial profiles, as flattop super-Gaussian or square-shaped beams, and is thus potentially able to compensate for the thermally induced aberrations of the laser medium.
