title: Continuous-wave far-infrared two-photon-pumped, single-photon-pumped, and Raman laser emission from 14NH3.
abstract: Continuous-wave laser emission has been obtained in (14)NH(3) by using different excitation techniques. Two-photon infrared-microwave pumping led to laser emission with offsets between the virtual level and a real level up to 3 GHz. Raman laser emission could be demonstrated with offsets between the virtual level and a real level tip to 0.56 GHz. A new coincidence between (14)NH(3) and N(2)O could be used to generate far-infrared laser emission by resonant single-photon pumping.
