The absolute Raman gain for the Q(1) vibrational Raman transition in H2 at 4155 cm−−1 has been measured at pump (Stokes) wavelengths of 532 (683), 477 (594), and 307 (351) nm using a pulsed pump and a cw probe laser, both of which were single frequency. Good agreement is found between the measured and calculated Raman steady-state gain coefficients. Empirical formulas are derived to calculate the Raman gain as a function of wavelength, density, and temperature.
