The article is devoted to the study of the effect of a two-micron fiber laser on biological tissue. The paper describes the results of experiments conducted using continuous and ultrashort pulse laser radiation with energies from 1.5 to 20 J in a spectral range of 2 microns on biological tissue. Experimental dependences of the depth and diameter of the impact zone on energy were obtained, and it was also found that the diameter and depth of the ablation and coagulation zone are fixed at an impact energy of ∼10 J in the pulsed mode. In general, the results of the work can be used to optimize procedures for the treatment of biological tissue using laser exposure.
