摘要
激光强度时空分布测量对分析评价强激光大气传输效应和光束控制能力具有重要意义.光电阵列探测法具有时空分辨能力高、响应灵敏度高和测量误差低等优点,是目前最可靠的高能激光强度时空分布测量方法.一款光电探测单元由激光衰减取样装置、冷却系统、积分球衰减器、光纤衰减器、光电检测检测模块和数据处理终端组成.基于该光电探测单元构建光电阵列探测器,可实现大面积、高能量和高时空分辨力的激光强度时空分布测量,可为高能激光光电阵列探测器的研制提供技术支持.
Abstract
The accurate measurement of the temporal-spatial distribution of laser intensity is crucial for analyzing the atmos-pheric propagation effect of high-power lasers and evaluating the beam control and aiming ability of high-power laser systems.Currently,the most reliable method for measuring high-energy laser power intensity distribution is the photoelectric array de-tection method,offering high temporal-spatial resolution,response sensitivity,and low measurement error.A photoelectric de-tection unit comprises a laser attenuation sampling apparatus,cooling system,integrating sphere attenuator,optical fiber atten-uator,photoelectric detection module,and data processing terminal.Utilizing the photoelectric array detector based on this unit enables the measurement of large area laser spot,high-energy laser,and high temporal-spatial resolution,providing essential technical support for the development of high-power laser photoelectric array detectors.
