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

Abstract

A synchronously pumped D(2)gas-in-glass fiber Raman laser operating at 1.56 microm has been demonstrated. The active medium is molecular D(2) diffused into a 100-m-long conventional single-mode solid silica optical fiber. Synchronous pumping with a mode-locked 1.06-microm Nd:YAG laser (120-psec pulse width with 100-MHz repetition rate) produces 15-psec pulses at 1.56microm with peak output powers of 20 W.
