Optical limiting performances of acid blue 29 are investigated under irradiation by a 35 mW continuous wave He-Ne laser. The optical limiting behavior is investigated by using transmission measurement through samples with different concentrations. Our results show that the optical limiting efficiency is concentrations dependence. Induced self diffraction patterns are observed at relatively high intensities starting from 15 mW.
