Abstract

Optical fibers of 50-µm core diameter are investigated for high-quality beam delivery of moderate power (30 W cw) Nd:YAG laser light. The fiber output near-field profile is important for materials processing applications, but is dependent on the modal distribution within the fiber, together with any intermodal interference. Launch optics design, mode-coupling, and modulation techniques are investigated as methods of controlling this beam profile, together with any associated beam quality (M²) changes. As an example application, high-precision, small kerfwidth cutting of stainless steel is demonstrated. ©1996 Society of Photo-Optical Instrumentation Engineers.
