Sub-Poissonian laser
Fritz Haake, Sze Meng Tan, Daniel F. Walls · Physical Review A · 1990
By intermittently and periodically pumping N atoms and observing time-scale separation for pumping, emission, and photon leakage from the cavity a laser with up to 50%, sub-Poissonian photon statistics can be realized. We present a stroboscopic period-to-period description of such a laser and clarify how pumping and spontaneous emission can be eliminated and cavity damping be minimized as sources of photon noise.
