摘要

我们将象限光电二极管作为热致透镜补偿器和激光棒中楔形补偿器的波前曲率传感器。波前曲率分析仪的灵敏度达到λ/100。在100ps 0.5J×200Hz Nd:YAG激光器中，采用热透镜补偿器，输出光束发散度<1.5×DL。

Adaptive compensator of thermally induced lens with analyzer based on quadrant photodiode

We used a quadrant photodiode as a sensor of wavefront curvature in the compensator of thermally induced lens and wedge in laser rods. Sensitivity of the wavefrontcurvature analyzer λ/100 was achieved. Using of thermal lens compensator with such sensor provided output beam divergence <1.5×DL in 100ps 0.5J×200Hz Nd:YAG laser.
