Paper Abstract

An innovative method of optically combining the multiple emitters of high-power stripe laser diodes is presented. A multibeam integrator approach is used along with a means of optically rotating the emitters by 90 deg. The 90-deg 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 increasing the irradiance for laser machining applications.
