Abstract

We consider a single-mode dye laser with colored pump noise and white quantum noise. An analytical approach is applied to study the statistics of the intensity fluctuations for arbitrary correlation times of the pump noise. Full numerical solutions are compared with our approximation and previous approximations schemes. The present approximation scheme compares favorably over wide regimes in parameter space with the numerical data. \textcopyright{} 1996 The American Physical Society.

Relation between photon statistics and pumping fluctuations in a dye laser

T. S. Kim, E. C. Gage, L. Mandeļ

Measurements of the photon-number fluctuations in a single-mode dye jet laser are compared with solutions of the equations of motion with colored pumping and white spontaneous-emission noise. A search of parameter space for best agreement between theory and experiment shows that the experimental results cannot be well modeled by a theory with white pumping noise, although the correlation time is small, but can be modeled with colored noise. This emphasizes the importance of not treating the pumping fluctuations as δ correlated, even for time-independent quantities.

Analysis of a dye-laser model including quantum noise

M. Aguado-Gómez, Maxi San Miguel

An analytical study of a dye-laser model which includes quantum white noise and nonwhite pump fluctuations is presented. The extension of an earlier approximation to include quantum noise gives a unified picture of the statistical properties of the laser light for negative pump parameters. These include intensity fluctuations and discontinuous changes of the most probable intensity. An alternative approximation (obtained within the same scheme) is discussed for situations above threshold.

Dye-laser fluctuations: Comparison of colored loss-noise and white gain-noise models

M. Aguado-Gómez, Emilio Hernández-Garcı́a, Maxi San Miguel

A single-mode dye-laser model incorporating pump white noise through gain-parameter fluctuations is analyzed. It includes a fluctuating saturation term. Intensity fluctuations, a first-order-like transition, and intensity correlation functions are calculated and discussed. It is found that effects previously claimed to be a consequence of the presence of colored noise in the context of loss-noise models can be also explained by white gain noise, except for the existence of two time regimes in the early decay of intensity correlation functions.

Effects of colored pump noise on intensity correlations of a single-mode dye laser

Paul D. Lett, Edward C. Gage

Recent theoretical analyses of the single-mode laser with colored-noise pump fluctuations have allowed the detailed prediction of the short-time behavior of the intensity autocorrelations of such a laser. In particular, a rounding off of the intensity correlation function on the time scale of the correlation time of the pump fluctuations has been predicted. We present results from experiments performed on a single-mode dye-laser system that clearly confirm these predictions. Numerical simulations of the laser Langevin equations including the colored-noise pump fluctuations are used to fit the experimental results.

Modeling of dye-laser photon statistics

Fabio Marchesoni

We propose a model for dye lasers operating at resonance with a non-Gaussian fluctuating pump parameter. Analytical and numerical results are compared with recent experimental measurements on the intensity fluctuations of a dye laser and with previous theoretical predictions based on a fluctuating pump parameter of finite correlation time.

Noise in dye laser transients

Shu Zhu

Statistical properties of dye laser transients are analyzed by first-passage-time technique. Both pump and quantum fluctuations effece the establishment of steady states in a dye laser. These two kinds of noise play different roles in laser transients. Meanwhile it is difficult to discern them since the pump fluctuations are six orders of magnitude larger than the quantum noise. In this paper a model of single mode dye laser with pump fluctuations simplified by white noise is presented and the analytic results of the mean, variance and skewness of first-passage-time distributions are obtained through a Fokker-Planck equation. Compared with experimental measurements and curves from Monte Carlo simulations, excellent agreement is obtained.
