Center for Photonics and Nanoelectronics researchers use new phase-locking technique to achieve record-high output power
Terahertz lasers could soon have their moment. Emitting radiation that sits somewhere between microwaves and infrared light along the electromagnetic spectrum, terahertz lasers have been the focus of intense study because of their ability to penetrate common packaging materials (such as plastics, fabrics, and cardboard) and to be used for identification and detection of various chemicals and biomolecular species—and even for imaging of some types of biological tissue without causing damage. Fulfilling terahertz lasers’ potential for use hinges on improving their intensity and brightness, achieved by enhancing power output and beam quality.
