摘要

为了准确测量皮秒量级超短脉冲的信噪比，扩大测量仪器的可测动态范围，针对高功率超短激光脉冲在相关过程中产生参量荧光的问题,研制了一台重复频率扫描测量的三阶相关仪，并在皮秒域短脉冲光学参量啁啾脉冲放大(OPCPA)抽运源上开展了测量技术研究。研究实验表明，通过采用大角度非共线匹配方式，消除了参量荧光对测量过程的影响，进而通过结构优化降低了背景噪声的影响，使可测动态范围达到107左右。由于互相关技术的非对称性，该测量系统可同时提供时间波形的分析功能。测量结果显示，激光脉冲前沿与双曲正割(sech)型曲线比较吻合，而脉冲后沿与高斯型曲线吻合得比较好。

Abstract

In order to obtain accurate signal to noise ratio (SNR) measurement of picosecond ultrashort pulse and enlarge the range of pulse SNR measurement, a repetition frequency scanning third-order correlator is built, which considers the problem of parametric fluorescence induced by ultrashort high-power laser pulses in correlated process. Besides, the measurement technology is carried on picosecond short-pulse optical parametric chirped pulse amplification (OPCPA) pump source. The results show that the impact of parametric fluorescence on the measurement is largely eliminated by large-angle noncollinear phase matching, furthermore, by reducing the background noise the dynamic range can achieve about 107. Because of the asymmetry of cross-correlation technique, the correlator can also analyze temporal profile. The results indicate that pulse front edge is coincident with sech type curve, and pulse back edge has good agreement with Gauss type curve.
