THz Quantum Cascade Laser
Terahertz quantum cascade lasers operate at 1-5THz. Coherent polarized THz radiation results from direct stimulated electronic transitions within the conduction band of semiconductor heterojunctions. The source states that all terahertz lasers require cryogenic cooling. Puxian Technology supplies ALPES THz quantum cascade lasers for semiconductor, biomolecular structural characterization, communications and environmental-monitoring research.
