Coherent Radiation Generation in (7.9÷8.7) µm and (11÷14) µm Regions by Rotational Raman Scattering in Deuterium

Stimulated rotational Raman scattering of C02 laser radiation in ortho-D2 provides a high-power coherent source in the infrared region from 11 to 14 ~m. A peak output energy of -1 J has been obtained for a pump energy of 4.0J. Threshold energies have been compared with those of para-H2 measured in the same apparatus and experiment scaling factors are discussed
