wavefront distortion

There are a lot of factors leading to wavefront distortion, and influencing beam quality. In order to achieve high coupling efficiency between laser beam and target, the phase must be precisely controlled to achieve the special focal irradiance profile.

高功率固体激光装置中有诸多因素导致波前畸变，影响光束质量；为实现高效的束靶耦合，必须精密控制波前以实现特定焦斑分布。

The detection and reconstruction of wavefront distortion are the main contents of MCAO.

波前畸变的探测与重构是多层共轭自适应光学的研究核心，文中分析了层析、定向层和多视场定向层等实现波前畸变探测与重构的方法；

Adaptive Optics was a synthesis disciplines that correct the wavefront distortion in a real time.

自适应光学（Adaptive Optics）是一门实时校正波前畸变的综合性学科。

In high power laser system, a small size phase-distortion wavefront measure is necessary to compensate and control the wavefront of laser beam with intermediate frequency.

在高功率激光系统，激光束小尺度相位畸变波前探测是实现激光束中频段波前补偿与控制的重要前提。

Using the Shack-Hartmann wavefront sensor, the thermal distortion of the substrate, the single-layer dielectric thin films with different thickness, and the multi-layer dielectric thin films with different multilayer thin films ( YbF 3/ ZnSe) irradiated by CO 2 laser are studied experimentally.

在此基础上，利用夏克哈特曼波前传感器对介质基底样品、不同厚度的介质单层膜样品以及不同膜系的YbF3/ZnSe介质多层膜样品在10.6μmCO2激光辐照下的热畸变进行了实验研究。
