小畸变光强衰减器 激光光强空间分布测量 intensity-attenuator and imaging system with small measurment of the spatial intensity distribution
摘要
介绍了用于测量星光装置激光远场空间分布的高衰减倍率的光强衰减与成像系统。它是高功率激光远场实时监测系统的重要组成部分。衰减器衰减倍数可以在10-2～10-12间变化,衰减成像系统在给定条件下引入的附加波像差被控制在2倍衍射极限之内,总的波像差小于2λ/3。
Abstract
The Intensity—attenuator and imaging system with high attenuation used for measuring the far-field spatial intensity distribution of “Xiang Guang Ⅱ” laser system is introduced. Intensity—attenuator is an important part of the far-field real time detecting system for high power laser. The attenuation call vary from 10-2 to 10-12 and the induced wave aberration of attenuator and imaging system is controlled within the 2× diffraction limit. namely 2λ/3 wave aberration under given experimenta1 conditions.
