A single-color circularly polarized laser beam is focused into pressurized hydrogen to generate rotational stimulated Raman emission. After being corrected to a linearly polarized beam, this two-color laser beam is passed through a dye amplifier and is focused into pressurized hydrogen, again to generate multifrequency laser emission by the two-color stimulated Raman effect. The laser beam is further confined in a resonator, which enhances intracavity intensity leading to increased efficiency. In these experiments, more than 11 rotational lines are generated simultaneously at 5 atm, and many additional vibrationally shifted rotational lines are generated at 9 atm.
单频圆偏振激光束聚焦到高压氢气中以产生旋转受激拉曼发射。在被校正为线偏振光束后，该双色激光束通过染料放大器并再次聚焦到高压氢气中，通过双色受激拉曼效应产生多频激光发射。激光束进一步被限制在谐振器中，这增强了腔内强度从而提高了效率。在这些实验中，在5个大气压下同时产生了超过11条旋转谱线，在9个大气压下产生了许多额外的振动频移旋转谱线。
