Abstract
We briefly review the studies devoted to development and applications of terahertz and multiterahertz quantum cascade lasers on intraband transitions in quantum wells of semiconductor heterostructures, which appeared in the last 5–7 years. Such lasers developed recently for the frequency band 3.5-70 THz find more and more applications in spectroscopy, communication, etc. We describe the first experiments performed at the Institute of the Physics of Microstructures of the Russian Academy of Sciences on studying the parameters of multiterahertz cascade lasers provided by our European colleagues.
