Abstract
A laser having a line-narrowing output coupler. This output coupler reflects a portion of light generated in the gain medium and provides a spectral narrowing of that reflected light. A portion of the line narrowed beam is directed back into the gain medium for further amplification and a portion is transmitted as a part of the laser output. In a preferred embodiment, the laser is line narrowed in the rear as well as by the line narrowing output coupler.
