10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM2010). 2nd International Workshop on Thz Radiation: Basic Research and Applications (TERA 2010)
Terahertz-range intracenter silicon lasers have demonstrated significant progress over past decade in expanding the frequency operation range, in manipulation of a silicon matrix as well as in lowering of optical pump threshold. While terahertz gain realized in silicon lasers has been already defined, optical losses in the active media have not been yet measured experimentally. We applied continuous...
Terahertz stimulated emission (4-6 THz) from optically excited group-V donors (phosphor P, antimony Sb, arsenic As, bismuth Bi) in axially compressed silicon crystal has been studied. As shown CW laser operation of P, Sb, As donors become reachable due to the laser threshold decrease induced by the stress.
