摘　　要：研究了在放大激光脉冲的噪声测量中，二阶相关技术和三阶相关技术的差别。理论分析显示，三阶相关技术不仅可以显示噪声脉冲的正确位置，而且具有比二阶相关技术更高的测量精度。The differences between autocorrelation and triple correlation are studied in contrast ratio measurement of amplified laser pulses. Theoretical analysis shows that triple correlation can not only locate the right position of the noise pulse, but also has higher accuracy than autocorrelation. These results are verified by numerical calculation.
