Abstract
Single-pass operation of a D2 gas-in-glass fiber Raman laser operating at 1.56-μm wavelength, pumped by a Nd:YAG laser operating either Q-switched or mode-locked has been demonstrated. The group velocities in the single-mode host fiber at the pump wavelength (1.06 μm) and the Raman-shifted wavelength (1.56 μm) were matched, thereby providing long interaction lengths and concomitant efficient conversion of pump light to 1.56-μm radiation.
