The physical mechanism is the dynamical process of the relaxation of a laser from an unstable state to a steady stable state. We present an analysis of this process based on the study of the nonlinear relaxation time. Our analytical results are compared with numerical integration of the stochastic differential equations that model this process.2 p.application/pdfeng(c) The American Physical Society, 1991Fluctuacions (Física)Mecànica estadísticaProcessos estocàsticsFluctuations (Physics)Statistical mechanicsNonlinear relaxation time and the detection of weak signalsinfo:eu-repo/semantics/article60151info:eu-repo/semantics/openAccess
