High power diode array module has been fabricated. The epitaxial structure is an InGaAs/GaAsP strain compensated single quantum well. The laser bars are made with a filling factor of 84.6%. The module's quasi-continuous wave (100 microseconds, 1000 Hz) peak power can reach to 88.6 W at a current of 100 A. The central wavelength is 1050 nm and the full width at half maximum is 4.2 nm.
