ABSTRACT:
A series of quantum well laser chips is mounted on a frame disposed in an external cavity opposite a tuning element. Selected chips are optically pumped by a diode laser or diode laser array. 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 TEM.sub.00 radiation.
