In this paper, a combinative technology of harmonic solid-state laser and stimulated Raman scattering (SRS) has been investigated to obtain multi-wavelength laser output with definite power. Multi-order harmonics of a Nd∶YAG laser, second harmonic (SH), thrird harmonic (TH) and fourth harmonic (FH) have been employed to generate multiple Raman lines by pumping the gases of hydrogen, methane, etc. The output Raman lines cover waveband from ultraviolet to near infrared. The characteristics of frequently used Raman gases, methane and hydrogen have been discussed, both have advantages and disadvantages. The mixture gas of these two gases makes up the overlarge frequency shift of hydrogen on the one hand, and restrains the decomposition of methane on the other hand. The rare buffer gases and the mixture gas have also been employed to optimize the Raman output. The table of 24 Raman lines is listed in this paper, including 13 lines of rather strong power. Multi-wavelength Raman lasers integrating the technologies of SRS and harmonic solid-state lasers could be applied in lidar and other application field.
