| Abstract: | The relationships between thermal aberration and the deflection of the MEMS-DMs,the voltage of MEMS-DMs poles are deduced.An experimental platform of adaptive optics system for compensating the aberrations in laser resonators was set up.The experimental results show that wave front aberration of laser could be corrected effectively by exerting different control voltage on 37 drive electrodes of deformable mirror and changing bend degree of mirror face,and provide essential experimental evidence for application of adaptive optics based on MEMS-DMs in thermal aberration correcting system. |
