…emit in the terahertz region is being used by astronomers working at the South Pole in Antarctica. Coherent's SIFIR-50 laser, which produces 50 mW in the 0.3-7 THz range, was originally developed for the US military. Now the optically-pumped system is an essential component of a terahertz receiver…
