Query: Femtosecond laser pulse train interaction with dielectric materials   We investigate the interaction of trains of femtosecond microjoule laser
pulses with dielectric materials by means of a multi-scale model. Our
theoretical predictions are directly confronted with experimental observations
in soda-lime glass. We show that due to the low heat conductivity, a
significant fraction of the laser energy can be accumulated in the absorption
region. Depending on the pulse repetition rate, the material can be heated to
high temperatures even though the single pulse energy is too low to induce a
significant material modification. Regions heated above the glass transition
temperature in our simulations correspond very well to zones of permanent
material modifications observed in the experiments.
