Optical power in excess of 25 W from one facet has been obtained from a 1-cm monolithic AlGaAs laser array for a pulse width of 150 μs (quasi-cw operation). The array consists of twenty 40-stripe lasers spaced along the bar, with etched grooves between each region to prevent transverse lasing and amplified spontaneous emission. About 80% of the facet width is utilized for active laser emission.
