摘　　要：Continuous wave（CW） operation of long wave infrared（LWIR） quantum cascade lasers（QCLs） is achieved up to a temperature of 303 K. For room temperature CW operation, the wafer with 35 stages was processed into buried heterostructure lasers. For a 2-mm-long and 10-μm-wide laser with high-reflectivity（HR） coating on the rear facet, CW output power of 45 m W at 283 K and 9 m W at 303 K is obtained. The lasing wavelength is around 9.4 μm locating in the LWIR spectrum range.Continuous wave（CW） operation of long wave infrared（LWIR） quantum cascade lasers（QCLs） is achieved up to a temperature of 303 K.
