T-rays at room temperature

INNOVATIONS IN LASER technology have led a team of Harvard research­ers to create the world's first electri­cally-pumped semiconductor source of coherent Terahertz (THz) radiation at room temperature.

Previously, electrically-pumped, Tera­hertz semiconductor lasers were im­practical to use, due to the significant amounts of cryogenic cooling needed to make them work properly, but the new findings could prove to be a break­through in the field of Terahertz (THz) radiation, or T -rays.
