• Filamentation of infrared femtosecond pulses in Tellurite glass is reported, leading to the generation of a supercontinuum generation spanning from the visible up to 4μm. The angular distribution of the supercontinuum shows clear evidence of conical waves generation, in particular, in the visible region. Moreover, taking advantage of the spatio-temporal self-focusing effect occurring in the Tellurite glass, a twofold pulse shortening is demonstrated. Tellurite glass appears as a very convenient, versatile and promising medium for femtosecond nonlinear optics in the infrared region. •supercontinuum from the visible up to 4μm in Tellurite glass.•the angular distribution of the supercontinuum shows conical waves generation.•the experimental results are in good agreement with the numerical simulations.•a twofold temporal self-compression of the pulse is reported.
