Paper Abstract

We describe the design, growth by atmospheric pressure metalorganic chemical vapor deposition (MOCVD), processing and characterization of single quantum well separate confinement strained layer InGaAs-GaAs quantum well lasers designed for high power operation at emission wavelengths near 1064 nm. Threshold current density is reduced by 39% for long cavity devices through design optimization. Broad area lasers operate at high cw (> 5 W) and pulsed (> 20 W) powers, with low threshold current density and high power conversion efficiency. Index guided ridge waveguide lasers show stable single spatial mode operation over a wide range of output power and temperature.
