摘要

高功率固体激光装置的波前校正通常采用自适应光学或衍射光学的方法

但这些方法的应用都有一定的困难.小磨头数控抛光加工技术已逐渐得到广泛的应用

用它来实现大口径高功率固体激光装置的静态波前畸变校正提供了解决此问题的新思路.文章给出了校正试验模型、试验过程和结果.波前畸变由校正前的PV值4.59 λ(λ=632.8 nm)

RMS值0.938 λ下降到校正后的PV值0.43 λ

RMS值0.075 λ.校正的效果是相当明显的

证明了其应用的可行性.

Abstract

Optics or diffraction is usually used for wave front error correction of high po wer solid laser facility. But there are still some diff iculties in applying these technologies in practice. The use of a small lap top comput er contro lled optical finishing (CCOF) for correcting the wave front error of a large ape rtur e high power solid laser facility provides a new solution to this problem. The experimental result showed that the wave front error decreased from PV 4.59 λ(λ=632.8 nm) RMS 0.938 λ to PV 0.43 λ RMS 0.075 λ and it is passible to use CCOF for wave front error correction.
