Abstract Get PDF(in Chinese)

We use the 1064 nm laser as pumping light to obtain the 1248 nm laser via wavelength conversion based on stimulated Raman scattering in high pressure CO2 gas. By optimizing the pressure of CO2 and focal length of lens, we obtain the maximum conversion efficiency of 36.6% and the maximum pulse energy of 82 mJ for the first order Stokes light (S1, 1248 nm).
