Abstract

The thermal lens induced in an a-cut BaWO4 crystal by stimulated Raman scattering is measured using lateral shearing interferometry. The strength of the lens is proportional to the Stokes output power. For light polarized parallel to the a-axis, and a Stokes mode radius of 120 μm, the lens is negative and highly astigmatic: −0.8 D W−1 in the plane parallel to the a-axis and −7.7 D W−1 in the plane parallel to the c-axis. The implications of this thermal lens for Raman laser design are discussed.
