Abstract: An apparatus and method that reduces laser speckle by using stimulated Raman scattering in an optical fiber (710, 718). The fiber core diameter and length are selected to achieve a desired output color. An adjustable despeckler is formed by combining two optical fibers (710, 718) in parallel and adjusting the amount of light in each path with the help of a rotatable waveplate (704) and a pola7rizer (706) as a beam splitter. A homogenizing device (722) illuminates a projector (724).

Abstract: An optical system which includes some or all of the following parts: a laser light source which illuminates a spatial light modulator such that optical characteristics are preserved; a stereoscopic display which has a polarization-switching light source; a stereoscopic display which includes two infrared lasers, two optical parametric oscillators, and six second harmonic generators; two light sources processed by two parts of the same spatial light modulator; a method of assembly using an alignment plate to align kinematic rollers on a holding plate; an optical support structure which includes stacked, compartmented layers; a collimated optical beam between an optical parametric oscillator and a second harmonic generator; a laser gain module with two retroreflective mirrors; an optical tap which keeps the monitored beam co-linear; an optical coupler which includes an optical fiber and a rotating diffuser; and an optical fiber that has a core with at least one flat side.
