Abstract

Picosecond Parametric Raman crystalline anti- Stokes laser at 503 nm with collinear beam interaction of orthogonally polarized Raman components in calcite at tangential phase matching under 532 nm 20 ps laser pumping is investigated. For the first time the highest anti-Stokes (503 nm) conversion efficiency of 30 % close to the theoretical limit of about 40 % at overall optical efficiency of the anti-Stokes generation of up to 3.5 % is obtained. The highest anti-Stokes 503 nm pulse energy was 1.5 uJ.
