摘要:

When a short pulsed, high power laser is focused on any solid target,a portion of the material is instantaneously exploded into its vapor. Laser ablation is a term to describe this explosive laser material interaction. Various processes like ejection of ions,atoms and clusters, thermal evaporation, plasma initiation and expansion, interaction between the plasma and the target, may result.
