摘　　要：提出并实验研究了采用旋转中空角体棱镜作为光学延迟器的二阶实时光学自相关器。用于飞秒锁模掺钛蓝宝石激光器输出的脉冲测试表明,该相关器运转稳定、可靠。提出了用计算机对所测相关曲线进行误差补偿的概念。A new type of autocorrelator with a rotating retroreflector is reported. Optical path length alteration is produced by introducing a rotating retroreflector into one arm of autocorrelator. It can be used to realize the real time monitoring and measurement of femtosecond laser pulses. The conception of error compensation is introduced in autocorrelation measurement, and the interferential correlation curve is corrected with a computer.
