摘要：

We demonstrate quantum cascade lasers at an emitting wavelength of 4.6 mu m, which are capable of room temperature, high power continuous wave (cw) operation. Buried ridge geometry with a width of 9.8 mu m was utilized. A device with a 3 mm cavity length that was epilayer-down bonded on a diamond submount exhibited a maximum output power of 1.3 W at room temperature in cw operation. The maximum output power at 80 K was measured to be 4 W, with a wall plug efficiency of 27%. (C) 2008 American Institute of Physics.
