Paper Abstract

Unimorph DMs are attractive for laser beam shaping due to their advantages of simplicity, compact, low cost and large stroke. This paper reports a novel unimorph deformable mirror used for laser beam shaping. The developed DM consists of both an inner actuator array and an outer ring actuator. The inner actuator array is used for aberration correction, while the outer ring actuator is used to generate an overall defocus bias. A laser beam shaping experimental setup with a He-Ne laser was constructed. The correction capability of the DM is demonstrated by simulation and experiment.
