摘要：

Based on stimulated Raman scattering (SRS), we study a method for obtaining multispectral laser. The frequency doubled Nd:YAG laser at 532 nm is used as the pumping light, and the high pressure CO2 is used as Raman active medium, and ten different Stokes lasers between 390 nm and 755 nm arc generated simultaneously. By optimizing CO2 pressure, the maximum photon conversion efficiencies for first-order Stokes (Si, 571 nm), second -order Stokes (S2, 621 nm) and third-order Stokes (S3, 683 nm) reach 36.6%, 19. 6 /o and 11.2%, respectively.
