摘要：

Stimulated Raman Scattering (SRS) is important method of laser frequency conversion. The cascade SRS and four wave mixing (FWM) will happen, if the peak power of the pump laser is high enough. The cascade SRS and FWM could generate multiple Stokes beam with equal spacing in frequency domain, which is optical frequency comb (OFC). In this paper, the (OFC) generated by SRS of CO2 is reported and the spectral range of this OFC covers from 0.4 mu m to 1.5 mu m. Experimental conditions were optimized to achieve intense OFC beam. When laser of 1064 nm was used as pump source, 12 anti-Stokes and 2 Stokes were generated; if laser of 532nm was used as pump source, 5 anti-Stokes and 4 Stokes were generated, and the photon conversion efficiencies of S1 (574 nm), S2 (624 nm) and S3 (683 nm) could be more than 10% simultaneously.
