Abstract

We have observed stimulated rotational Raman scattering (SRRS) from para-H₂ pumped by a CO₂ TEA laser operating on the strong P- and R-branch transitions of both the 9.4- and 10.6-μm bands. Small signal gain for the Stokes wave in excess of 80 dB has been obtained for TEM₀₀ pump powers of 8.5 MW in a multiple-pass gain cell cooled to liquid-nitrogen temperatures.
