Paper Abstract

For study of the dynamics of laser evaporation of model normal and tumoral biotissues the method autodyne detection (self-mixing on laser resonator) of back scattered light from the irradiated zone was used. Biomodels of tumors using of laboratory animals and gelatin models were used. These biomaterials were irradiated by focused beam of CO2 laser 5-10 Watts power with concurrent recording autodyne signal. The level of autodyne signal at laser cutting of multi-layer gelatinous models varies from 1.5 to 3 times at difference of water content in layers from 10 to 30% respectively. The level of autodyne signal as the average power spectrum of this signal varies in different degrees depending on the type of normal and tumoral biotissues at its laser evaporation.
