Abstract

An innovative method of optically combining the multiple emitters of high power stripe laser diodes is presented. A multi-beam integrator approach is used along with a means of optically rotating the emitters by 90 degrees. The 90-degree rotation allows better balancing of the optical invariants in the slow and fast axis directions, making it easier to "circularize" the image for coupling into fibers or to increase the irradiance for laser machining applications.
