摘要	We report on the lasing characteristics of a two-dimensional (2D) vertical-cavity surface-emitting laser (VCSEL) array with three In(0.2)GaAs/GaAs(0.92)P QWs emitting at 977 nm. The contribution of a large-bandgap barrier material, GaAsP, to improve the output power was investigated. More than 123W of pulsed peak power at 110 A was achieved, corresponding to 24.6 kW/cm(2) of power density and 1.11 W/A of slope efficiency. The thermal effect dependence of the characteristics of the array was illustrated. Moreover, the device performance was estimated by a functional method using a p-parameter.
