Abstract
An apparatus and method for despeckling that includes a pulsed green laser, a green laser diode assembly, and stimulated Raman scattering light formed in an optical fiber. The stimulated Raman scattering light is divided into green light and red light. The green light from the stimulated Raman scattering is combined with the green laser diode assembly to form a green primary light. The red light from the stimulated Raman scattering light forms a red primary light. The green primary light and the red primary light are used to project a digital image.
