Mode Competition in Miniature Optically Pumped NH3Far Infrared Laser
The semiclassical density matrix equation of four energy levels was solved. Then by means of iteration method, the output power increment ratio of V 2∶a→s P(5, 4) to a→s Q(5, 4) transition in miniature optically pumped NH 3 molecules far infrared superradiant laser (mini NH 3 OPFIRL), which was pumped by CO 2 10R(6) line, was calculated. The calculation showed that the mode competition between the V 2∶a→s P(5, 4) and V 2∶a→s Q(5, 4) in superradiant mini NH 3 OPFIRL led to the elimination of V2:a→s P(5,4) and V2:a→s S(5,4) in superradiant mini-NH3-OPFIRL led to the elimination of V2:a→s P(5,4) transition branch. The theoretical calculation was consistent with the experimental result.
