High-Power Ridge-Waveguide Tapered Diode Lasers at 980nm

Abstract
High-power ridge-waveguide tapered InGaAs-AlGaAs lasers emitting at 980nm were fabricated.Lasers with a total length L=1850μm and different lengths of the ridge waveguide Lrw were processed to study the influence of the straight section on the spatial mode filtering.When Lrw is 450μm,the devices have the optimized maximum output power and beam quality,and the output power P is 4.28W.The beam propagation ratio M2 is 3.79 at 1W.-
