Patent ID: 7633562

Claim:
A projection display, comprising: at least one optically pumped semiconductor (OPS) laser, said laser including a semiconductor gain medium located with a resonator including one mirror spaced from the gain medium, said gain medium being optically pumped in order to generate fundamental radiation and wherein the resonator is configured so that the fundamental (TEM 00 ) mode size at the gain medium is smaller than the pump beam spot size at the gain medium whereby the laser generates laser radiation in multiple transverse modes in both orthogonal (X/Y) axes perpendicular to the propagation axis of the delivered laser radiation, said laser further including a nonlinear crystal within the resonator for doubling the frequency of the fundamental radiation; a spatial light modulator for spatially modulating said radiation from said OPS-laser in accordance with a component of an image to be displayed; and projection optics for projecting said spatially modulated light onto a screen on which said image is to be displayed.
