Paper Abstract

We demonstrate how closed-loop adaptive optical system can be used to obtain a good focused beam. The optimal correction of the high-power beam aberrations can be found by use of genetic and hill-climbing algorithms. A bimorph mirror is used as a wavefront corrector and CCD camera at the focal plane of the lens is a sensor. This adaptive system can correct for the low-order slow changing aberrations without any measurements of the wavefront.
