Abstract

980 nm low divergence semiconductor lasers with optimized large optical cavity (LOC) structure was designed for high power single mode operation. The InGaAs strained quantum well (QW) laser material was grown with solid source molecular beam epitaxy (MBE) system. The high efficiency single mode lasers were fabricated with 3 μm stripe width and 750 μm cavity length. The maximum output power of 70 mW was achieved at 100 mA injection current at room temperature, with the maximum slope efficiency of 0.89 W/A and typical vertical divergent angle of 28°. The output power of the device reached 190 mW under 250 mA current and the device could operate at 70 ℃ reliably.
