Ablation holes in tape targets induced by ultra-intense laser pulses

29 febrero 2024

We present a theoretical modelling able to predict the dimensions of mm-sized through-holes produced in interactions of the 1 PW high-power 30 fs Ti:Sa laser VEGA-3 with tape targets. We find that sizes of through-holes can be calculated by assuming that the full heat transferred from the laser-heated electron population to the target by electron–electron collisions drives the evaporation of target material. We demonstrate the good reproduction of experimental results.
