Abstract We studied the near-field formation mechanism of a silver oxide thin film sandwiched between protective layers using a pump probe with nanosecond laser pulse irradiation and tapping-mode tuning-fork near-field scanning optical microscopy. A multilayer composed of ZnS{endash}SiO{sub 2}/Ag{sub 2}O/ZnS{endash}SiO{sub 2} showed abnormal optical nonlinear properties compared to ordinary third-order nonlinear materials. The Ag{sub 2}O layer played a role in generating a strong light scattering center in a reversible chemical reaction in only a small area of the multilayer, and the optical near field produced about the scattering center was 40 times stronger than that produced by an antimony layer instead of Ag{sub 2}O. {copyright} 2001 American Institute of Physics.
