Heuristic stochastic model of mirrorless optical bistability

Abstract
A heuristic microscopic two-level-atom model with fluctuations is developed to explore, theoretically, the effect of fluctuations on mirrorless optical bistability. In stochastic models, bistability appears as a bimodal distribution function. We show that the predictions of bimodality and bistability are the same in the heuristic and semiclassical (nonstochastic) microscopic models.
