Abstract
A pulsed laser preferably a tunable laser having a narrow band width is provided which has a high conversion efficiency at a high repetition rate. The laser includes a diffraction grating located in the laser's optical cavity. The optical cavity is defined by a mirror and diffraction grating or two mirrors with a diffraction grating therebetween. A tunable laser material is located within the optical cavity between the mirror and the diffraction grating. Desirably the diffraction grating is movably mounted within the optical cavity so that a beam of a presected wave length diffracted by the grating can be directed across the laser material. Optionally where two mirrors define the optical cavity, one of the mirrors or the grating or both can be movably mounted within the optical cavity. Preferable the movable grating and the movable mirror are rotatably mounted.
