Saturation effects on intensity fluctuations of a laser with multiplicative white noise
Jin Wang, Shiqun Zhu, Jianping Yin
Abstract
The saturation effects in a single-mode laser with multiplicative white noise are investigated through a full saturation laser model. The corresponding Fokker-Planck equation is transformed to a radial Schr\"odinger equation and the intensity correlation time and effective eigenvalues are calculated. Compared with experimental measurements, excellent agreement is obtained and the cavity decay rate is also determined. Relatively large errors occur in the third-order theory and the measured data.
