The formation of waveguides in doped with Eu nanoporous glass in the course of it's irradiation with focused femtosecond Cr:Forsterite laser pulses is studied. Propagation of intense laser radiation in such waveguides was accompanied by supercontinuum generation, which was not observed in pure porous glass at the same conditions.
