Abstract

Handheld fiber laser welding is increasingly replacing arc welding as the technology of choice, driving strong demand for components that enable cost-efficient designs. In a first step, this trend has driven the development of multi-mode edge-emitting laser diodes in the 9xx nm wavelength range that, depending on emitter width, nowadays routinely achieve output power levels in the range of 35-45 W. We report on our recent developments of even more powerful single emitter laser diodes at Coherent Corp. to support novel and even more cost-efficient fiber laser architectures. Our newest generation of edge-emitting devices provides reliable output power levels in CW operation of up to 65 W from a 320 μm-wide emitter.
