Paper Abstract

Ultrashort laser pulses provide high power at low energy which is very promising to obtain precise microstructures inside and on the rear side of the transparent materials. Decreasing the pulse duration from several ps into the sub-ps range, we noticed strong differences in the processing and non-linear behavior. We performed experimental investigations on laser beam propagation through wide-band gap materials at high peak powers. We present recent results on different types of bulk modifications generated inside several different transparent materials and focus our attention on pulse duration dependent observations in a range between 0.2 and 4 ps.
