Refraction system for compensating for strain double refraction takes into account thermally induced lens action in laser media

摘要

First (1) and second (2) solid body laser substances (SBLS) are optically pumped, cooled via a jacket surface and operated symmetrically in reference to their polarization-changing properties. A polarization rotator (6) fits between the SBLS along with first (3) and second (4) optical devices for forming a beam by adapting a beam diameter and a divergence angle. An independent claim is also included for a structure for compensating for strain double refraction by taking into account thermally induced lens action in laser media.
