摘要：

A similar to 2.1 -mu m laser is within an atmospheric transmission window and can be used in remote sensing. In this work, a 1064-nm laser was used as the pump source, pressurized hydrogen was used as the Raman active medium, and a dual-wavelength similar to 2.1 -mu m Raman laser was generated. The 2147-nm laser was generated by a combination proc-esses of stimulated vibrational Raman scattering and stimulated rotational Raman scattering, while a 2132-nm laser was generated by stimulated S-branch vibrational Raman scattering. Optimizing experimental conditions yielded a maximum pulse energy of 76.1 mJ, a peak power of similar to 9.2 MW, and a photon conversion efficiency of 29.8%.'(c) 2023 Optica Publishing Group
