High-power hybrid two-dimensional surface-emitting AlGaAs diode laser arrays

Two-dimensional surface-emitting AlGaAs diode laser array modules, each containing two 1 sq cm hybrid arrays, have been fabricated and tested. For quasi-CW operation, peak output powers greater than 300 W/sq cm appear to be easily achievable at repetition rates up to 500 Hz. The measurements also indicate that CW output powers of 100-150 W/sq cm can be achieved from these arrays.
