Abstract
A method and apparatus for beam combining for multiple multimode semiconductor laser diodes includes achieving beam combining in radiant space to provide a directional laser beam with a uniform high radiant intensity level distribution over a large area at a long distance from the source. The method uses more than one broad area high-power multimode semiconductor laser diode and individual optics for collimation, and includes combining the beams of these emitters to provide a relatively homogeneous radiant intensity beam at a long distance for applications such as directed energy delivery, free-space laser communication, and directional infrared countermeasures.
