Abstract :
An optical power output of 134 W from one facet and power conversion efficiencies as high as 49% have been obtained from monolithic AlGaAs laser arrays with 1 cm emitting widths for 150^s pulse widths (quasi-CW operation). The arrays have etched grooves to prevent transverse lasing and amplified spontaneous emission.
