Paper Abstract

The paper reports on the design and development of an innovative high power and high brightness laser diode module that is capable of delivering more than 350 W at 976 nm in a standard 0.2 NA 50/125 fiber and 95% of power is in 0.15 NA. This module combines Everbright's multi-emitter modules assembled with 50 μm ridge width 976 nm laser diode chips through dense wavelength beam combining (DWBC) and polarization combining. The intrinsic wavelength stabilization of DWBC technology allows the use of the module for efficiently pumping Yb-doped fiber lasers.
