Scientists at MIT and the University of Waterloo have created anextremely powerful portable type of a device named a “quantum cascade laser”. This device is known to produce terahertz radiation in the in vitro conditions. The laser could widely be used in applications includingidentifying skin cancer and hidden explosives. The terahertz radiations generally was used to executereal-time imaging and quick spectral studythat require temperatures below 200K or lower. These temperatures could be obtained using huge equipment that cannot be used in laboratory setting. Additionally, the researchers have suggested that these lasers can work at 250K as well. Thereby, it is clear that even a portable and compact cooler is enough.

The terahertz quantum cascade lasers released by thesmall chip-integrated semiconductor laser deviceswere designed to work above 200K. The researchers overcame the challenges to prove the efficiency of the new technology. It is finally possible to have this compact portable terahertz imaging and spectral systems function outside the laboratory. The new system is likely to have a wide range application in medicine, security, biochemistry, and other fields. The lasers released are thinner compared to human hair and few millimeters in length. Furthermore, this quantum well structures with accurate customized engineering to tackle all the barriers. The staircase patterned interior electron structuring helps meticulously emit photon.

The most important design is the high barriers that help avoid leakage of electrons and in turn, increase temperature. The leakage is the major reason for the breakdown of the system and thus, the researchers though of sporadically testing the higher barriers to yield superior results.As the high electron scattering and taller barriers were dangerous, the design was optimized using a direct phonon scheme that helps easily depopulate the electrons by means of phonon scattering to a ground state and this entire process repeats in the staircase structure. In the medical and other industrial settings, the applications of the new portable system can provide real-time imaging and discovery of foreign objects in a product for assuring its qualityandsafety.
