| 中文摘要 | 高重复频率热容主振荡功率放大器(MOPA)激光系统的工作过程一般只持续几秒至几十秒,在此过程中系统输出光束的波前畸变是动态变化的。采用环路径向剪切干涉(CRWSI)技术对高重复频率热容MOPA系统波前畸变的变化过程进行检测,并对系统的总体结构进行了设计。搭建了一个简化的实验系统,采用平凹透镜来代替光放大器产生波前畸变,并由此对环路径向剪切干涉仪的测量精度进行了验证。结果表明,实验测量结果与理论计算值之间的峰值误差为7.8%(0.02λ)。; The operating time of high repetition rate heat capacity master oscillator power amplifier (MOPA) laser usually lasts for only several seconds or tens of seconds. During this time, the wavefront distortion of the output beam is changing all the time. A method of sensing the wavefront of high repetition rate heat capacity MOPA system by a cyclic radial wavefront shearing interferometer (CRWSI) was proposed. The main structure of this system has been designed. A simplified experimental system was established. A plano-concave lens instead of the optical amplifier was used to generate wavefront distortion. Based on this system, the measurement accuracy of CRWSI was certified. The results show that the difference between the experimental result and the theoretical result is 7.8% (0.02λ). |
