Paper Abstract

Long life, high power and high repetition frequency 2D laser diode (LD) arrays are needed for pumping solid state lasers. The reliability of AlGaAs/GaAs high-power lasers has been studied. Over 1 X 109 operation shots in 4-stack 2D LD arrays with 350 W peak output power and over 1 X 1013 shots in single-stripe laser diodes with 2.3 W peak output power have been obtained. 2D LD arrays of 3.5 kW (emitting area 3.2 cm x 1.0 cm), 2.5 kW (emitting area 1.0 cm x 1.0 cm) and 2.2 kW (emitting area 6.5 cm x 0.12 cm) were demonstrated under quasi continuous wave operation.
