超短光脉冲波形测量

Waveform measurement of ultrashort optical pulses

提出一种适合于测量各种超短光脉冲波形的新方法。这种方法不需要对待测光脉冲波形作任何假设,根据实验中同时测得的超短光脉冲的自相关曲线和频率光谱分布,可以给出光脉冲的实际波形和频率啾啁的详细信息。该方法已应用于主动锁模半导体激光器产生的微微秒光脉冲测量。

We have proposed a novel method which is applicable to any kind of pulses and makes possible to measure the details of frequency chirping as well as the pulse shape, using simultaneously measured SHG auto-correlation curve and the frequency spectra of the pulses, without any prerumption for the pulse shape. The method has been applied to the actively mode-locked diode laser pulses.
