Abstract

Preliminary investigations into the potential for automatic spatial-mode optimization in tehrmally distorted soild-sate lasers using deformable mirrors are presented. A 37 element adaptive optic mirror has been used intracavity to control the oscillation mode profile of a diode-laser pumped Nd:YVO4 laser. Spatial mode and output power optimization are demonstrated by closed loop computer control of the deformable mirror using a modified hill-climbing algorithm.
