Steady-State Analysis of a Two-Mode Laser System with Cross-Correlation Between Real and Imaginary Parts of Quantum Noise

Dai Zu-cheng, Xiang You-Lin, Mei Dong-Cheng

An inhomogeneously broadened two-mode laser system with cross-correlations between the real and imaginary parts of quantum noise is considered. The Fokker–Planck equation of the system is derived by the phase-locking method. The steady-state probability distribution, the mean light intensity, the normalization autocorrelation function, and cross correlation function are calculated. The results indicate that: (i) The cross-correlation between the real and imaginary parts of quantum noise can cause the stationary probability distribution from one peak structure to two extrema structure when the laser system is operated above threshold; (ii) The cross-correlation between the real and imaginary parts of quantum noise enhance the light intensity fluctuation and decrease the laser output when the laser system is operated below or near threshold; (iii) The effect of the cross-correlation between the real and imaginary parts of quantum noise is very weak on the stationary properties when the laser system is operated far above threshold.

Effects of correlations between the real and imaginary parts of quantum noise on intensity fluctuation for a saturation laser model

Yuehong Li, Mei Dong-Cheng

This paper studies the effects of cross-correlations between the real and imaginary parts of quantum noise on the laser intensity in a saturation laser model. It derives the analytic expressions of the intensity correlation function C(τ) and the associated relaxation time T (C) in the case of a stable locked phase resulting from the cross-correlation λ q between the real and imaginary parts of quantum noise. Based on numerical computations it finds that the presence of cross correlations between the real and imaginary parts of quantum noise slow down the decay of intensity fluctuation, i.e., it causes the increase of intensity fluctuation.

Analysis of the Intensity Fluctuation of Saturation Laser Model in the Real and Imaginary Parts of the Cross-correlation of Quantum Noise

Treated at the quantum noise of the real and imaginary parts of crosscorrection and saturation laser mode,an analysis of the intensity correlation function and the associated relaxation time is made in the case of a stable locked phase resulting from the cross-correlation between the real and imaginary parts of are derived by means of projection operator method.Based on numerical computations it is found that the presence of cross-correlations between the real and imaginary parts of quantum noise causes the intensity fluctuation to increase.A slowing-down phenomenon exists in the sense that increases as a function of.Thus the decay of intensity fluctuation becomes slow.
