Paper Abstract

An experimental study of a prototype optically-pumped distributed-feedback resonant-periodic- gain vertical-cavity surface-emitting laser (DFB-RPG YCSEL) is reported. Both cw and pulsed conditions are investigated. The results obtained on bare wafer samples without any heat sink indicate that very high output power should be possible. Thermally limited cw output power of 6.7 mW cw was obtained with 10-?m diameter of the pumping beam. Under pulsed conditions, the output power of 8.5 W over 7 ns pulsewidth with power conversion efficiency of 10.5% was achieved. To our best knowledge, this is the highest peak power density ever reported for any semiconductor laser.
