用脉宽15ns、重复频率20kHz、中心波长为1064nm的全固态Nd:YVO4激光抽运2km的G652单模石英光纤产生受激拉曼散射(SRS)。得到分离的前三级斯托克斯谱和四级以上自1300nm至1700nm(光谱仪的截止频率)的超宽连续谱,并在光纤的零色散波长1310nm附近(四至六级斯托克斯频段上)观察到明显四波混频现象。
Stimulated Raman Scattering (SRS) was generated using a G652 single-mode silica fiber with a pulse duration of 15 ns, repetition frequency of 20 kHz and center wavelength of 1064 nm. The first three Stokes spectra were separated and the ultra-wide continuum spectra from 1300 nm to 1700 nm (the cut-off frequency of the spectrometer) above the fourth level were obtained. At the zero-dispersion wavelength of the fiber around 1310 nm (four to six Stokes bands ) Obvious four-wave mixing was observed.
