摘要：

A model that simulates the dynamics of the temperature field formed by pulsed laser radiation inside a biological structure containing blood vessels is developed. The threshold conditions of denaturation of vessel walls and subsequent blocking the blood flow are determined based on the thermochemical concept. The possibility of application of a pulsed modulation of the radiation for increasing the homogeneity of coagulation of vessel walls and reducing the risk of damage of tissues caused by the phase transition is considered. The modulation frequency range of radiation that ensures the realization of this effect is determined.
