Abstract

We present a detailed study of the spatial properties of spectral continuum generation in glasses. We show that the conical emission which accompanies filamentation in the glasses is a Cerenkov-based effect resulting from self-focusing. A theoretical analysis of the angular dependence of the emission based on a moving focal point is in good agreement with the experimental data.
