Abstract

The time-dependent solutions of the Fokker-Planck equation for a single-mode laser with white noise loss fluctuations are studied theoretically. Both the multiplicative and additive noise sources are included in the treatment, and they have comparable strengths. Experiments were carried out on a single-mode He-Ne laser. Multiplicative noise was introduced by applying a noise voltage on an intracavity loss element. The steady-state correlation functions of the laser were determined from the photoelectric correlation measurements, and their behavior with multiplicative noise strength was studied in the pump parameter range a = –10 to a = 10. The results of these measurements are compared to the theoretical predictions.
