Induced photon statistics in three-level lasers

T. Yu. Golubeva, Yu. M. Golubev, D. A. Ivanov

The statistical properties of light emitted by a three-level laser are theoretically investigated. In the model considered the three-level medium is coherently excited by another laser having arbitrary photon statistics. It is shown that under certain conditions the photon statistics of the three-level laser is determined by that of the exciting laser. This feature is referred to as induced photon statistics. It is proposed to use this phenomenon to analyze the statistics of a laser involved in a feedback process. Arranging an experiment in a way such that the laser of interest serves as a coherent pump for the probe three-level laser one is able to directly observe the statistics of the feedback-controlled laser by simply detecting the induced photon statistics in the three-level probe system. The analysis of the operation of such two-laser system presented demonstrates, in particular, that the feedback itself is unable to produce a nonclassical state of light which is in complete agreement with the conclusion of Wiseman and Milburn [Phys. Rev. A 49, 1350 (1994)].

Two-Level Laser Light Statistics

Jacques Arnaud, Fabrice Philippe, Laurent Chusseau

The statistics of the light emitted by two-level lasers is evaluated on the basis of generalized rate equations. According to that approach, all fluctuations are interpreted as being caused by the jumps that occur in active and detecting atoms. The intra-cavity Fano factor and the photo-current spectral density are obtained analytically for Poissonian and quiet pumps. The algebra is simple and the formulas hold for small as well as large pumping rates. Lasers exhibit excess noise at low pumping levels.

Quantum theory of light generation by two-level atoms without inversion

В. Н. Горбачев, Andrew I. Trubilko

When pumping produces atomic coherence on working levels or atomic polarization two-level atom can generate the light without inversion. In such systems one- and two-photon generation of the light is considered for the laser and micromaser operation. Using Lamb-Scully model generalized for coherent pumping statistics of the light is considered. Two-photon laser operation is found to be phase squeezed and perfect noise reduction can be achieved. In maser a set of steady state of subpoissian photon statistics is found. For these states the noise reduction up to 60 percent can be obtained if inversion is zero. Phase squeezing in micromaser is found.
