Abstract

The paper reports on the design, manufacturing and preliminary characterization of a new compact and high beam quality multi-emitter laser module able to deliver about 300W in a standard 105/125 fiber with 0.22 numerical aperture but with 95% of power in NA = 0.15. The layout exploits a proprietary architecture and uses a plurality of chips emitting at two different wavelengths combined through spatial, polarization and wavelength multiplexing. Given its small footprint and low ownership costs, the module has been specifically devised as the basic building block of laser sources for metal powder additive manufacturing machines.
