SOLID-STATE LASER DEVICE BASED ON A TWISTED-MODE CAVITY AND A VOLUME GRATING

摘要

The present invention describes a solid-state laser device based on a twisted-mode cavity and a volume grating, which comprises: a pumping source for emitting pump light; an optical resonator, which comprises: a cavity mirror, which is a high reflective mirror for introducing the pump light into the optical resonator; an output coupler, which is a reflective volume Bragg grating spaced away from the cavity mirror; a twisted-mode cavity, which includes: a first wave plate, located at one side close to the pumping source; a second wave plate, located at another side far away from the pumping source; a gain medium, located between the first wave plate and the second wave plate for generating a fundamental frequency laser; a focusing unit, located between the pumping source and the optical resonator for focusing the pump light emitting from the pumping source to the optical resonator.
