    "abstract": "We consider three- and four-level atomic lasers that are either incoherently\n(unidirectionally) or coherently (bidirectionally) pumped, the single-mode\ncavity being resonant with the laser transition. The intra-cavity Fano factor\nand the photo-current spectral density are evaluated on the basis of rate\nequations.\n  According to that approach, fluctuations are caused by jumps in active and\ndetecting atoms. The algebra is considerably simpler than the one required by\nQuantum-Optics treatments.\n  Whenever a comparison can be made, the expressions obtained coincide. The\nconditions under which the output light exhibits sub-Poissonian statistics are\nconsidered in detail. Analytical results, based on linearization, are verified\nby comparison with Monte Carlo simulations. An essentially exhaustive\ninvestigation of sub-Poissonian light generation by three- and four-level atoms\nlasers has been performed. Only special forms were reported earlier.",
