Compact all-fiber gas Raman light source based on hydrogen-filled hollow-core photonic crystal fiber pumped with single-mode Q-switched fiber laser
A compact all-fiber gas Raman light source is reported. The gas Raman cell is based on hydrogen-filled hollow-core photonic crystal fiber. A single-mode Q-switched fiber laser is used as the Raman pump source. The Stokes pulse is much narrower than the pump pulse. The Stokes pulse duration and conversion efficiency were studied.
