1.7 µm all-fiber gas Raman laser source

2020 
We report here the first tunable pulsed all-fiber 1.7 μm gas Raman laser source. It is based on hydrogen-filled hollow-core photonic crystal fibers by rotational stimulated Raman scattering. The maximum average Stokes power of 1.61 W is obtained with optic-to-optic conversion efficiency of about 23%.
