Synchronously pumped D_2 gas-in-glass fiber Raman laser operating at 156 μm

Abstract
A synchronously pumped D2 gas-in-glass fiber Raman laser operating at 1.56 μm has been demonstrated. The active medium is molecular D2 diffused into a 100-m-long conventional single-mode solid silica optical fiber. Synchronous pumping with a mode-locked 1.06-μm Nd:YAG laser (120-psec pulse width with 100-MHz repetition rate) produces 15-psec pulses at 1.56 μm with peak output powers of 20 W.
