Theoretical study of a two-photon double-beam laser. Academic Article uri icon


  • A nondegenerate two-photon laser in a cascade three-level atomic system is studied. The difference between the laser and that derived from an effective Hamiltonian is discussed. Photon number distributions about field 1 are presented. The effects of field 2 on field 1 are studied in detail. Field 2 can play a role of gain enhancement or gain reduction for field 1. This is due to two actions of field 2: reducing the population of the intermediate level and changing the detuning really acting upon field 1, which is caused by the ac Stark shift. 1988 The American Physical Society.
