Patent ID: 8345717

Claim:
A continuous wave laser comprising: a resonator cavity; at least a first reflector and a second reflector said first and second reflectors being located at opposite ends of the resonator cavity; a laser gain medium located in the resonator cavity for generating a continuous wave fundamental beam which resonates within the resonator cavity when pumped by a pump beam from a pump source external to the resonator cavity; a solid Raman-active medium positioned in the resonator cavity for Raman shifting the fundamental beam to produce a continuous wave Raman beam which resonates within the resonator cavity; a non-linear medium positioned in the resonator cavity for frequency converting the continuous wave Raman beam to a converted wavelength to produce a continuous wave converted beam; wherein the resonator cavity is a high finesse resonator cavity at the wavelength of the continuous wave fundamental beam and the Raman beam and a low finesse resonator cavity at the wavelength of the continuous wave converted beam.
