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.

The design, fabrication, and characteristics calculation of 980-nm optically pumped semiconductor disk laser are reported. The laser combines a vertical cavity semiconductor laser with a partically reflecting out coupler and an external cavity for mode control. Pumped by 808-nm diode laser, the disk laser directly generates a linearly polarized, circularly symmetric, diffraction-limited beam with watt-level power. Calculation shows the laser with active region of InGaAs/GaAsP/AlGaAs system can operate at near 500-mW in a single transverse mode.
