Abstract

The paper reports on the design, manufacturing and preliminary characterization of a new family of compact and high beam quality multi-emitter laser diode modules capable of delivering up to over 400W in a 135/0.15 fiber. The layout exploits a proprietary architecture and is based on innovative narrow linewidth high-power DBR chips, properly combined through spatial, polarization and wavelength multiplexing. The intrinsic wavelength-stabilization of these DBR chips allows the use of the developed modules not only for direct-diode material processing but also in pump sources for ytterbium-doped fiber lasers without the need of external stabilization devices.
