<p>A series of quantum well laser chips (22) is mounted on a frame (14) disposed in an external cavity opposite a tuning element (20). Selected chips are optically pumped by a diode laser or diode laser array (28). The laser light from one of the facets of a selected chip is collimated by a lens onto the tuning element. The tuning element disperses the light and a portion of the dispersed light at the single frequency is coupled back to the facet causing the chip to generate single frequency TEMoo radiation.</p> |
