Synchronously pumped anti-Stokes Raman-parametric laser on a CaMoO4 crystal

We study generation of a crystalline anti-Stokes Raman-parametric laser with collinear phase-matching under intracavity synchronous pumping by a 1064-nm, passively Q-switched, longitudinally mode-locked Nd³⁺:YAG laser. As an active medium, use is made of a CaMoO₄ crystal, which has optimal birefringence for the angular phase-mismatching insensitive Stokes-anti-Stokes Raman-parametric four-wave interaction at a matching angle of 71° and an angular matching width of 4°. The conditions are determined for generating a single ultrashort anti-Stokes pulse at a wavelength of 973 nm with a pulse duration of 9 ps and an energy of up to 9 μJ.
