13.3 W quasi-continuous operation of 0.99 /spl mu/m wavelength SCH-QW InGaAs/GaAs/InGaP broadened waveguide lasers

摘要

An output power of 13.3 W at 0.99 /spl mu/m wavelength was obtained in the quasi-continuous wave regime from a 3 mm long, 100 /spl mu/m aperture InGaAs/GaAs/InGaP SCH QW laser with broadened waveguide. A differential efficiency of 0.72 was demonstrated at 15/spl deg/C for these devices with a series resistance of 0.025 /spl Omega/.
