We report numerical and experimental results obtained with an optical setup that simulates the heating and cooling processes expected in a multi-slab high-average-power laser head. We have tested the performance of an adaptive optics system consisting of a photo-controlled deformable mirror (PCDM) and a Shack-Hartmann wavefront sensor for the effective correction of the generated wavefront aberrations. The performance of the adaptive optics system is characterized for different layouts of the actuator array and for different configurations of the heating mechanisms. The numerical results are benchmarked using a PCDM, which allowed us to experimentally compare the performances of different deformable mirrors.
我们报告了通过一种光学装置获得的数值和实验结果，该装置模拟了多片式高平均功率激光头中预期的加热和冷却过程。我们测试了由光控变形镜（PCDM）和夏克 - 哈特曼波前传感器组成的自适应光学系统的性能，以有效校正产生的波前像差。针对致动器阵列的不同布局以及加热机制的不同配置，对自适应光学系统的性能进行了表征。使用PCDM对数值结果进行了基准测试，这使我们能够通过实验比较不同变形镜的性能。
