Formation of a Single Microstructure and Ablation into a Transparent Dielectric Material under Subnanosecond Laser Irradiation

详细

The formation of a jet and a frozen microstructure after the subnanosecond laser irradiation of a thick film from the side of a transparent substrate has been explained in numerical simulation. Such simulations were previously performed only for the irradiation of a thin film by an ultrashort pulse. The results obtained in this work also allow the description of physical effects at the ablation of a metal into a liquid in the theoretically unstudied case of a subnanosecond pulse of great applied interest.
