Thermal lensing in high-power ridge-waveguide lasers
2007
2007 International Conference on Numerical Simulation of Optoelectronic Devices
Outline • motivation and laser structure • experimental results • theoretical model • simulation results • conclusions Motivation • fundamental-spatial mode diode lasers with an output power in the 1-W range of interest for a variety of applications • requires narrow lateral waveguide defined by small effective index step to cut-off higher order modes • at higher output power appearance of instabilities like kinks in light-current characteristics beam steering appearance of higher order modes •
