我们报道了Q（1）（0）跃迁（v = 1？0，J = 0？0)在固体仲氢中。我们进行测量，泵浦与连续波倍频YAG激光在532 nm和观察的探测激光束的直接放大的第一斯托克斯跃迁在683 nm。在泵浦强度为46 kW/cm（2），相互作用长度为1 cm时，获得了2.3 ± 0.2的大单程放大系数，稳态拉曼增益系数为18 ± 3 cm/MW。
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.
