Abstract
A laser in an embodiment of the present invention is disclosed that includes a laser pump source, a pump-beam coupler (PBC) coupled with the laser pump source, a laser gain medium coupled with the PBC, a second-harmonic generator (SHG) coupled with the laser gain medium; and an output coupler coupled with the SHG.
Claims22
A solid state laser system, comprising:
- a pump source that includes a wavelength stabilizer that is integrated into the pump source;
- a laser medium positioned after the pump source, wherein said laser medium comprises Nd:YVO4 having a near uniform Nd3+ doping level between and including approximately 0.2 at. % and 2 at. %;
- a frequency doubler positioned after the laser medium.
A solid state laser system, comprising:
- a laser gain medium;
- an output coupler positioned after the laser gain medium, wherein the output coupler has a first surface that is coated with an HR, and a second surface that is coated with an AR, wherein the first surface has a radius of curvature of approximately 85 mm, and wherein the output coupler is a plano-concave output coupler.
A laser system, comprising:
