Ortho-deuterium Raman laser using the S/sub 0/(2) rotational transition in the mid-infrared region

摘要

Based on a calculation for the Raman gain coefficient of the S/sub 0/(2) transition in ortho-D/sub 2/, we have demonstrated the generation of first Stokes waves in the 15-16-/spl mu/m spectral region. Use of ortho-D enriched by a catalytic converter enabled us to realize efficient conversion at room temperature. Stokes energies as high as 400 mJ were obtained.
