We report the experimental evidence of Stochastic Resonance in the polarized emission of a semiconductor laser. We give for the first time in a real system a complete characterization of the phenomenon based on the residence times probability density, with quantitative agreement with existing theories. By using an accurate choice of the indicator, we also provide a clear evidence of the bona fide resonance. Moreover, we are able to introduce and investigate for the first time a Three-state Stochastic Resonance. © 2000 American Institute of Physics.
