We report a steady-state Raman gain measurement of the Q_(1)(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/cm~(2), with an interaction length of 1 cm, giving a steady-state Raman gain coefficient of 18±3 cm/MW.
