ScienceDaily News Release: Researchers Hone Radiation Source For Terahertz Devices; Potential Applications In Medicine, Remote Sensing, Imaging And Satelli

From a news release from Lehigh.
"Terahertz (THz) frequencies, ranging from 0.1 to 10 THz, have potential applications in medicine, remote sensing, imaging and satellite communications, but are nonetheless one of the most under-utilized frequency ranges. That is because the THz range lies between the microwave frequency range and the near-infrared and optical frequency ranges, in which conventional semiconductor devices are usually operated ...Ding and his research group, which includes four Ph.D. candidates, one M.S. candidate and two post-doctoral researchers, have developed a method of focusing two high-frequency lasers to generate tunable and coherent THz waves in the range of 58 to 3540 microns.
