Quantitative understanding of skin tissue ablation from UV to NIR with a new plasma model

A plasma model was used for quantitative understanding of skin tissue ablation from ultraviolet radiation to near infrared radiation. The thermal ionization of chromophores in skin tissue and its effect on the generation of free seed electrons was investigated. Thermal ionization was caused by transient temperature rise in chromophores during the short period of a laser pulse. The plasma model was found to be effective in explaining soft tissue ablation processes in the wide spectral region.
