A closed-loop adaptive optical system based on a genetic algorithm is developed. This system consists of a deformable mirror, a computer, beam splitter, wavefront sensor, and high voltage driver. The genetic algorithm adjusts the control voltages of 37 independent electrodes to vary the shape of the deformable mirror surface such that the aberration of laser beam can be compensated by deformable mirror...
Thermally induced optically-distortion effects are one of the main impediments to be overcome in developing high power solid-state lasers. To compensate the dynamic aberration of laser beam, an intra-cavity adaptive optical system was developed. A beaconing light was introduced to measure the wavefront aberration of intracavity laser beam and an MEMS deformable mirror was used to improve the wavefront...
