Abstract
Heavy metal-oxide glasses containing lead and bismuth were prepared, and their picosecond third-order nonlinear (NL) optical characteristics were investigated. NL refractive indices of ≈10−18m2∕W at 1064nm were measured. Negligible NL absorption was verified and, as a consequence, the samples present a good factor-of-merit for photonic applications.

From the applied point of view transparent NL glasses have many advantages compared to inorganic crystals and organic materials because of their fast response times, small linear losses, and negligible two-photon absorption coefficient, ␣2, for wavelengths in the infrared
