Abstract

The electronic and nuclear contributions to the third order nonlinearity of glasses are separated using 100 fs pulses with a time-resolved heterodyne optical Kerr effect technique. The time evolution of the nuclear contribution is in very good agreement with results deduced from the Raman spectra. A direct estimate of the relative strengths of electronic and nuclear contributions is made. The ratio between the two response function is ∼5/1 in Tellurium oxide glass sample. The validity of our method to separate these two contributions has been confirmed in different glasses.
