摘要：

We report the realization of a semiconductor injection laser based on intraband transitions with emission wavelengths extending beyond the atmospheric windows. The structure uses the quantum cascade scheme with "chirped'' superlattices as active material. Laser action in pulsed operation is achieved at lambda similar or equal to 17 mu m up to 150 K, with peak output powers of similar to 12 mW at cryogenic temperatures.
