Operating characteristics of high continuous power (50 W) two-dimensional surface-emitting lase array

Monolithic two-dimensional surface-emitting laser (SEL) arrays suitable for both optoelectronic and high power applications were fabricated utilizing a 4- mu m*450- mu m InGaAs single mode real refractive index guided gain cavity with 90 degrees and 45 degrees ion milled facets. A total CW output power exceeding 50 W was achieved at lambda approximately=944 nm from a monolithic 16*94 2-D SEL array. The 50-W CW output power level is approximately ten times greater than previously demonstrated from a 2-D monolithic SEL array. Greater than 150 h of continuous operation of a 2-D SEL array at 25 W CW was demonstrated.<
