Theoretical study of quasi continuously tunable optically pumped NH3 laser

摘要

The electric dipole transition enhancement affect of the Hyper-Raman process was studied theoretically. It was possible to get a quasi continuously tunable FIR laser by using IR-microwave two-photon pumped NH3 system. The tuning range of the FIR laser would be larger than 2 GHz, if the cavity was used instead of waveguide as the sample tube.
