Single crystals of tin dioxide synthesized by a hydrolysis reaction of stannic chloride are submitted to open-aperture Z-scan measurements at 532 nm. The two-photon absorption coefficient of the crystal is determined-to be 7.6±1.3 cm/GW. The value is larger by about three times than that predicted theoretically. One of the reasons for the discrepancy is given as the applicable limit of the theory in which a two-band model is assumed in the analysis.
