Abstract
Quantum cascade (QC) lasers are semiconductor lasers based on intersubband transitions and on electrons emitting one photon per stage as they cascade through a periodic quantum well structure. Results are presented demonstrating the high power room temperature pulsed operation from 5 to 11.6 μm, with peak powers ranging from 200 to 50 mW. Distributed feedback QC laser is also discussed. Room temperature single mode pulsed operation is obtained in these devices at wavelengths approximately 5 μm and approximately 8 μm with broad single model temperature tuning of approximately 60 nm and peak powers approximately 60 mW. Structures with loss and index gratings is also discussed.
