| Abstract: | The spectral characteristic of an optically pumped NH_3 molecules FIR laser isstudied by a F-P interferometer and a Michelson Interferometer. We verify that whenNH_3 molecules are pumped by CO_2-9R(16)line,a radiation by Raman transitions of twophotons is produced.Wheh the pressure of NH_3 gas increasing,the interaction of theRaman transitions increase,then the radiation is enhanced and the radiation spectrum isbroadened. |
