NOISE PROPERTIES OF A BEAM PROPAGATING THROUGH AN ATOMIC VAPOR

[摘要] Saturated absorption is examined theoretically to determine the extent to which this process can lead to an increase in the intensity noise of an intense laser beam as the beam propagates through an atomic vapor. Numerical results for the modification of the intensity fluctuations and the noise figure are presented for both incoherent and coherent incident light. The results show that although saturated absorption is a real process for the generation of excess noise, it is not sufficient to account for the noise observed in laboratory experiments.
