Abstract：We present a surface metal grating distributed feedback quantum cascade laser emitting at λ～8.3 μm and operating above 400 K in pulsed mode. A very high peak power of 463 mW at 290 K and still more than 18 mW at 400 K is achieved for a high-reflectivity-coated 13-μm -wide and 2.5-mm-long laser. Single-mode emission with a high side mode suppression ratio and wide temperature tuning range is observed. Such a high-power single-mode laser with a simple device process is important for practical applications.
