Abstract
Optically pumped type-II QW lasers emitting in the 5.4-7.1 -μm wavelength range and at continuous-wave (CW) temperatures up to 210 K are demonstrated. At 80 K, the maximum CW output power from a 40-μm-wide pump stripe is 48 mW at 5.41 μm and 31 mW at 6.05 μm. Epitaxial-side-down heat sinking is provided by a new diamond-pressure-bond mounting technique, which requires minimal processing and maintains topside optical access.
