Paper Abstract

The growth conditions and lasing characteristics of the optically barrier-pumped GaSb - based semiconductor disk laser (SDL) emitting near 2 μm in an external cavity configuration are reported. It is made of a GaSb/AlAsSb Bragg reflector, a Ga0.8In0.2Sb/GaSb multi quantum-well active region and an Al0.8Ga0.2As0.03Sb0.97 window layer. Using an intracavity SiC heat spreader, a cw output power in excess of 1.12 W has been achieved at a heat sink temperature of 0 °C.
