Abstract We have analysed the propagation of two continuous-wave Ar+-laser beams travelling in opposite directions in a two-component nonlinear heterogeneous medium (the polymeric blend PMMA-EVA), in a mirror retroreflection geometry. Bistable reflection associated with the laser-induced suppression of scattering is observed. This phenomenon has a thermal origin. Based on light- and heat-transport theory inside the material, a simplified explanation of the experimental evidence is presented, showing the conditions for the onset of optical bistability. Qualitative agreement with our experimental results is found.
