Abstract
An apparatus and method for despeckling that includes a green laser diode assembly, a pulsed laser with a repetition rate of less than 100 kHz, and stimulated Raman scattering light formed in an optical fiber. The laser diode light and stimulated Raman scattering light are combined to form a projected digital image. The green laser diode assembly or the pulsed laser is switched to improve the bit depth of the projected digital image.
