Abstract :
We demonstrate an average power of 2 mW at /spl lambda//spl ap/11.5 μm and 233 K, for a GaAs-based quantum cascade laser mounted on a Peltier cooler. Furthermore, a maximum operating temperature of 285 K has also been demonstrated. These results are attributed to the excellent intrinsic thermal characteristics of these lasers and good heat management, achieved through the structural design and epi-side down mounting. Measurements show a thermal resistance of 6.7 K/W at 233 K, in good-agreement with our models.
