摘要：

Optical fibers of 50-mu m 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 (M(2) changes. As an example application, high-precision, small kerf-width cutting of stainless steel is demonstrated. (C) 1996 Society of Photo-Optical instrumentation Engineers.
