利用CARS方法研究超短脉冲激光的脉冲宽度

Investigation on temporal features of ultrashort pulses using CARS technique

在理论上提出了利用两光束CARS/CSRS方法测量超短脉冲激光的三阶相关函数。实验上在几种样品中测量了CARS/CSRS的时间特性,得到了泵浦光脉冲,SCDL输出光脉冲以及受激喇曼散射光脉冲的宽度。

Third-order correlation function for the measurement of ultrashort laser pulse using a two-beam CARS or CSRS technique was proposed theoretically. The temporal features of two-beam CARS or CSRS in several samples have been measured The durations of the pumping pulse, the output pulse of SCDL and the stimulated Raman scattering pulse were determined experimentally.
