title: Precise measurement of the rotational Raman gain coefficient in para-hydrogen by the large-signal method.
abstract: The plane-wave gain coefficient of stimulated rotational Raman scattering in para-H(2) was determined for CO(2) laser-pumping pulses. Difficulties caused by lowered substantial gain for stimulated scattering in the infrared region were overcome by measuring converted energies instead of powers in the large-signal region. The measured gain coefficients showed excellent agreement with theoretical values.
