Abstract

A study was made of the role of iron impurity ions in the formation and decay of color centers in alkali-silicate glasses under conditions of multiphoton absorption of laser radiation. An investigation was carried out on sodium-silicate glasses which are typical representatives of crown glasses. In the experiments the glasses of the Na₂O:CaO:SiO₂ equals 22:3:75% compositions synthesized from materials of the `specially pure' grade were used. The impurity was introduced in the form of the compound Fe₂O₃ in amounts of 0.1% by weight into some of the samples. Oxidative conditions during synthesis ensured that the main part of the iron ions in the glasses was in the form of Fe³⁺. Since the band gap of alkali- silicate glasses is approximately 6 eV, the third and fourth harmonics of a neodymium laser were used for nonlinear coloration of these glasses. It was shown that an increase in the concentration of Fe₂O₃ enhanced the residual absorption by stable hole color centers and reduced considerably the lifetime of unstable electron color centers. Repeated irradiation of the glasses containing a small amount of the impurity increased the residual absorption, whereas the induced absorption (measured immediately after the action of a radiation pulse) did not change from one pulse to the next and was governed solely by the radiation irradiance. An increase in the Fe₂O₃ concentration destroyed this effect.
