Abstract: A laser line generator system that utilizes a light guide element to convert high energy coherent light generated by a high fill-factor laser diode bar into homogenous light, and utilizes one or more slow-axis relay lenses to image the homogenous light such that it forms a homogenous line illumination pattern on an illumination plane. The light guide utilizes parallel or down-tapered side walls to mix received coherent light in the slow-axis direction by way of total internal reflection. A Keplerian telescope including two cylinder lenses is optionally used in place of the slow-axis relay lens. Optional fast-axis lenses are used to assist in focusing the homogenous light at the illumination plane. The laser light generator forms, e.g., a single-pass imaging system for a scanning/printing apparatus in which the homogenous line illumination pattern is directed onto a linearly arranged series of spatial light modulators, such as Digital Micromirror Devices (DMDs).
