一种新型的产生频谱展宽的方法

A New Method of Ultrashort Superbroadening Generation

在亚毫米液芯波导的一系列实验中,当波导中注入苯和CS2时,用高功率锁模YAG倍频光脉冲泵浦,可形成总超展宽达约4000cm-1之多的超短脉冲。

In a series of works made with the submillimeter liquid core waveguide, a superbroadening as large as 4000cm-1 has been observed in a fiber filled with benzene and CS2, separately, when it is pumped by high power mode-locked YAG SHG pulses. Strong broadening towards the low frequency side and depletion of pump laser line are two of the main features of such superbroadening.
