EFFECTS OF QUANTUM-NOISE IN A DYE-LASER MODEL

The steady-state properties of a dye laser model with white quantum no ise and strongly colored pump noise are investigated. An effective dif fusion coefficient in the steady state is presented. Our coefficient d iffers from that of Fox and Roy [Phys. Rev. A 35, 1838 (1987)]. We com pare our results with the measurements and simulations of Lett, Short, and Mandel [Phys. Rev. Lett. 52, 341 (1983)], and the results of Fox and Roy, respectively. We find that the quantum noise plays an importa nt role in the steady-state analysis of laser fluctuations below and n ear threshold.
