ABSThACTPossibility of recording second-order nonlinear susceptibility in commercial andspecially synthesized lead-silicate glasses was investigated. It was be found effective photoinduced SHG in glasses with lead content from 10 to 40 mol%. Optical waveguides by ion-exchange were made in this glasses. Optimal content of Na2O in lead-silicate glasses for optical waveguides was found.Refractive index profiles were reconstructed by enhanced WKB-method using cubic splines.Propagation losses in all waveguides were less than 0.5 dB/cm.
