Description

This item was taken from the IEEE Periodical ' Continuous-wave type-II "QW" lasers emitting at /spl lambda/=5.4-7.1 μm ' Optically pumped type-II QW lasers emitting in the 5.4-7.1 -/spl mu/m 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-/spl mu/m-wide pump stripe is 48 mW at 5.41 /spl mu/m and 31 mW at 6.05 /spl mu/m. Epitaxial-side-down heat sinking is provided by a new diamond-pressure-bond mounting technique, which requires minimal processing and maintains topside optical access.
