自适应激光谐振腔模式象差的微机控制器

Microcomputer Controller for Adaptive Correcting of Laser Resonator Mode Aberrations

在Ｚｅｒｎｉｋｅ多项式的基础上，文中采用象差低阶模式的校正原理，构造三自由度自适应校正激光谐振腔模式象差的微机控制器。该控制器用等步长搜索方法，实现了ＩＭＭＤ算法，获得了满意结果。

Based on the Zernike polynomials,this paper uses correcting theory for lower order mode aberrations,and designs a microcomputer controller for adaptive correcting of laser resonator mode aberrations with three free doms.This controller realizes IMMD algorithm by equal step length searching,and good results have been achieved.
