Synchronously Pumped Anti-Stokes Parametric Raman Laser on a CaMoO4 Crystal

The generation of a crystalline anti-Stokes parametric Raman laser with collinear phase matching under intracavity synchronous pumping by a 1064-nm passively Q -switched longitudinally mode-locked YAG:Nd 3+ laser has been studied. A CaMoO 4 crystal is chosen as an active medium. This crystal has opt...

Description
Summary:The generation of a crystalline anti-Stokes parametric Raman laser with collinear phase matching under intracavity synchronous pumping by a 1064-nm passively Q -switched longitudinally mode-locked YAG:Nd 3+ laser has been studied. A CaMoO 4 crystal is chosen as an active medium. This crystal has optimal birefringence for matching Stokes–anti-Stokes parametric Raman four-wave interaction at a phase-matching angle of 71° and an angular phase-matching width of 4°, which is insensitive to angular phase mismatch. The conditions for generating a single ultrashort anti-Stokes pulse at a wavelength of 973 nm with a duration of 9 ps and energy of up to 9 μJ are determined.
