A two-dimensional laser source with high power, small size and the ability to suppress speckle noise is designed for projection. This laser source module is composed of an array of laser diodes and a lens array which can realize uniform rectangular beam without other optical elements. The source module is built in Zemax software. The influences of the factors including the divergence angle, the number, the interval of laser diode (LD), and the beam divergence angle after the micro lens on the light efficiency, the beam size, the illumination distance and the beam uniformity are studied. A two-dimensional laser source module for liquid crystal display (LCD) projection is built based on theoreical analysis.
