Picosecond third-order nonlinearity of lead-oxide glasses in the infrared -: art. no. 221904

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 approximate to 10(-18) m(2)/W at 1064 nm were measured. Negligible NL absorption was verified and, as a consequence, the samples present a good factor-of-merit for photonic applications. (c) 2005 American Institute of Physics.
