Research into a new type of laser will dramatically improve future devices used for sensing and in communications, according to scientists at the University.
In a paper recently published in Physical Review B, researchers from the Department of Physics demonstrate their work into bosonic lasers which emit terahertz radiation.
Such lasers have been around for years, commonly found in satellites, for environmental monitoring, astronomy, security and non-destructive testing, imaging, and medical applications. But they are considered bulky, impractical and expensive.
Through this latest study, the researchers demonstrate how such lasers could be exploited to improve their performance and, potentially, lead to the miniaturisation of future technological devices. The research showcases how, in the future, new 'bosonic lasers' emitting terahertz radiation could be fine-tuned to vary or minimise the power required by the laser or to alter the intensity of terahertz radiation.
Scientists are excited by terahertz technologies as they provide unprecedented sensing capabilities across biology, pharmacy, medicine, material science, environment monitoring, security, astronomy and communications.
From DNA chips, to skin-cancer diagnosis, laser surgery to explosives inspection, there are numerous potentials across every field. Information and communications technology also benefits from terahertz technology, including for wireless communication, high-speed data processing and satellite communication.
