Abstract
An end-pumping laser system, which includes a resonator and a single pumping radiation source. The resonator includes an input coupler, a lasing medium and an output coupler. The single pumping radiation source pumps radiation axially into the resonator. The input coupler of the resonator is a retroreflector having three orthogonal surfaces which is located coaxially with, and intermediate between, the resonator and the pumping radiation source. The retroreflector is oriented so that radiation from the pumping radiation source simultaneously impinges on the three orthogonal surfaces of the retroreflector.
Claims4
An end-pumping laser system, comprising:
- (a) a resonator, said resonator including:
- (i) an input coupler;
- (ii) a lasing medium for generating laser radiation;
- and
- (iii) an output coupler for allowing a portion of said produced laser beam to leave said resonator;
- and
- (b) a single pumping radiation source for pumping radiation substantially axially into said resonator for generating a produced laser beam;
- said resonator being characterized in that said input coupler is a retroreflector having three substantially orthogonal surfaces, said retroreflector being located substantially coaxially with, and intermediate between, said resonator and said pumping radiation source, said retroreflector being oriented so that radiation from said pumping radiation source simultaneously impinges on said three substantially orthogonal surfaces of said retroreflector.
