Photorefractive phase conjugator for Nd:YAG laser system

摘要

An external loop phase conjugate mirror with a 45 deg -cut rhodium-doped BaTiO_3 was constructed and characterized. the external loop is composed of an image-relay telescope, a 90 deg -image rotator and a phase modulator. A phase conjugated Nd:YAG laser has demonstrated 360 mJ
