Abstract

The paper presents and proves experimentally a four-stage physical model of laser destruction of biological tissue having absorption coefficient close to 10 cm^-1 and a great skeleton part. Thresholds of bone and liver laser destruction are defined experimentally at wavelengths of YAG:Nd³⁺ and YAG:Ho³⁺ lasers. Correlation of laser radiation energy density to destruction efficiency and invasion factor is studied.
