摘　　要：由于超短超强激光装置中光谱带宽较宽,使用传统的空间滤波器透镜组扩束会导致装置色差的积累,严重影响终端焦斑的质量。介绍了国内外用于超短超强激光装置中消除色差影响的主要技术与研究进展,对比总结了几种主要方案的优缺点,并提出了一种可动态精确补偿装置色差的方案,经实验验证已应用于实际工程中。最后对色差补偿的发展方向进行了分析与展望。Due to the wide spectral bandwidth of ultra-short and ultra-intense laser facility,the use of traditional spatial filter lens groups to expand the beam will cause the accumulation of chromatic aberrations of the device,which will seriously affect the quality of the terminal focal spot.In this paper,the main technology and research progress of eliminating chromatic aberration in ultra-short and ultra-intense laser facilities are reviewed,and both the advantages and disadvantages of several main schemes are compared and summarized.On this basis,a scheme for dynamic and accurate compensation of the chromatic aberration of the facility is proposed,which has been verified and used in actual engineering.This paper also analyses and prospects the development direction of chromatic aberration compensation.
