In this study, a detailed investigation of the dynamics of the generation of pre-pulse by post-pulses is presented, using single-shot self-referenced spectral interferometry (SRSI). The capability of SRSI in terms of the single-shot measurement of the temporal contrast of high-power laser systems has been experimentally demonstrated. The results confirm that the energy levels of the pre-pulses increase proportional to the square of the B-integral parametrizing the nonlinearity of the amplifier chain.

大功率激光系统中后脉冲产生的预脉冲的单次测量

在这项研究中，使用单次自参考光谱干涉仪（SRSI），详细介绍了由后脉冲产生前脉冲的动力学。通过单次测量大功率激光系统的时间对比，SRSI的能力已得到实验证明。结果证实，预脉冲的能级与B积分的平方成正比，从而放大了放大器链的非线性。
