JERUSALEM--(BUSINESS WIRE)--Yissum Research Development Company of the Hebrew University of Jerusalem Ltd., the technology transfer arm of the University, today announced that Professor L.D. Shvartsman and Professor B. Laikhtman, from the Racah Institute of Physics at the Hebrew University of Jerusalem, have invented a novel design of TeraHertz-ray, or T-ray, lasers. Using nanostructures which are based on semiconductors with special properties, the novel device will have 400 times higher gain than THz quantum cascade lasers, the only coherent T-ray sources existing today , This invention will make T-ray based cameras and spectrometers practical, ushering a new era in security and medical imaging.
