Conical uniaxial crystal laser based output of radially polarized beam

Of outputting a laser beam based on a conical radial polarization uniaxial crystal that is composed of: a uniaxial crystal conical mirror, the laser gain medium, the output coupler mirror plane and a pump source, the laser gain medium is located in the uniaxial crystal between uniaxial crystal and a bottom surface of the conical mirror plane output mirror, said conical mirror uniaxial crystal apex where no and ne are made of the conical mirror uniaxial crystal principal refractive indices of the light e o light, the uniaxial crystal of no and ne should satisfy the following conditions: laser of the present invention has a simple structure and good stability, high efficiency laser, high output power and beam quality specialty.
