Paper Abstract

A flexible focus variable beam expander system with adaptive optics is designed. In this system the adaptive mirror's focus is adjusted by regulating the pressure of mirror's cooling water. The change of mirror's curvature and focus is calculated with elasticity mechanics and the conception of wavefront aberration is cited to study the difference between ideal curvature and realistic one. The results of experiments is corresponding to the theoretical data.
