"Korenblit and Tankhilevich's own predictions for their CW magnon laser are for a threshold current exceeding 5000 Amps/cm.sup.2, and employing 10-100 Watts of input electrical power, where it might be possible to extract .about.10 mW of laser power for a single-stage laser and .about.1 Watt for a 100 stage laser. The required threshold current and input electrical power for output laser power exceeds other known solid-stage lasers for this wavelength range, where wavelengths should be in the 0.2 to 2.0 THz region, with a laser line width of .about.1 MHz.
"Moreover, currently most powerful THz emitters are relatively feeble. Cooled Quantum Cascade Lasers (QCL) lasers emit microWatts of power, with the best prospects being mW. The best research-level MMICs emit only 50 mW of power at 0.22 THz."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "According to one embodiment, there is provided a pulsed emitter of electromagnetic radiation having a frequency range of 0.1 to 10 THz, comprising: an electromagnetic radiation gain medium for generating electromagnetic radiation having the frequency range of 0.1 to 10 THz; and a pulse inducing element configured to induce an electromagnetic radiation pulse in the gain medium."
