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 ¹⁴NH₃ 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 Up to 0.56 GHz. A new coincidence between ¹⁴NH₃ and N₂O could be used to generate far-infrared laser emission by resonant single-photon pumping.
