摘要：
We report the results of experimental observation of increasing absorption optical bistability in highly concentrated aqueous solutions of toluidine blue dye. The thermal shift of the monomer-dimer equilibrium towards higher monomer concentration is identified as the nonlinear optical mechanism that ensures also the positive local feedback. A simple model that gives the criteria for the occurrence of this type of optical bistability and which enables selections of effective dyes is presented.
