abstract

We report laser filamentation in the bulk of chalcogenide glass with femtosecond laser pulses of energy on the nanojoule level. Spatially resolved measurements of the resulting refractive index modification are presented. The study of the pulse energy and focusing condition dependencies show that channels of positive refractive index variation of several millimeter length can easily be obtained.
