Abstract: The experimental researches of nonlinear-optical processes are carried out at distribution of femtosecond laser pulses in the microstructured fibres from a combination of leaden-silicate glasses. The analysis of the factors influencing efficiency of spectral transformation is carried out. On the basis of data received the conclusion is made that for the chosen materials and structures, length of a pumping wave (807 nm) essentially will defend on a rule of zero meaning dispersion of group speed.

Keywords: microstructured fibres, supercontinuum, leaden-silicate glasses, femtosecond laser radiation, group velocity dispersion.
