Abstract

A window-mirror structure has been applied by Zn diffusion to real refractive index guided self-aligned AlGaInP laser diodes for the first time. Both a high catastrophic optical damage level of 152 mW and a high slope efficiency of 0.83 W/A have been obtained, resulting in an extremely low operating current of 225 mA, for a pulse output power of 150 mW at room temperature.
