摘要

自衍射效应在飞秒激光领域有非常重要的应用，如提高飞秒脉冲的时域对比度、作为自参考光谱干涉脉冲测量法的参考光、作为频率分辨光学开关法的信号光等. 然而，具有较宽光谱带宽的飞秒激光在自衍射效应过程中产生的信号光存在明显的角色散，这给自衍射效应的应用带来不利影响. 本文研究发现通过在自衍射效应的一个光路中加入等腰直角棱镜，当到棱镜的入射角为23°时可以明显地减小飞秒激光脉冲自衍射信号的角色散. 这就为以后将自衍射效应更好的应用到飞秒激光脉冲的研究提供了有用的参考.

Abstract

Self-diffraction effect has very important applications in the field of femtosecond laser, such as to improve the temporal contrast of femtosecond pulses, to be used as the reference pulse of self-reference spectral interferometry, and as the signal of self-diffraction frequency-resolved optical gating, etc. However, in the self-diffraction signal of femtosecond pulses with a broadband spectrum angular dispersion exists obviously, which will limit the application of self-diffraction effect. In this paper, the self-diffraction signal angular dispersion of femtosecond pulses is obviously reduced, when a right-angle prism is located in the light path of an incident beam with an incident angle of 23° to the prism. The experimental result provides a useful reference for the application of the self-diffraction effect to the research of femtosecond laser pulse in the future.
