Abstract

We describe a closed-loop adaptive optical system with bimorph deformable mirror to obtain good focused laser beam. This adaptive system can correct for the wavefront aberrations without any measurements of the wavefront: we use M2-meter as a sensor for the feedback. Closed-loop software allows to measure focal spot with M2-meter and then to calculate voltages to be applied to corrector. The best focal spot can be reached by use of combined method based on genetic and hill-climbing algorithms. We demonstrate the use of such a system with water-cooled bimorph deformable mirror as a wavefront corrector on CW solid state Nd:YAG 1kW CW laser system.
