Abstract

We report a steady-state Raman gain measurement of the Q1(0) transition (v = 1 ← 0, J = 0 ← 0) in solid parahydrogen. We carry out measurements by pumping with a continuous-wave frequency-doubled YAG laser at 532 nm and observing the direct amplification of a probe-laser beam for the first Stokes transition at 683 nm. A large single-pass amplification coefficient of 2.3 ± 0.2 is obtained at a pump intensity of 46 kW/cm2, with an interaction length of 1 cm, giving a steady-state Raman gain coefficient of 18 ± 3 cm/MW.
