Paper Abstract

The laser scalpel with ellipsoidal, parabolic, conical and truncated conical tips, and laser scalpels without exiting optics system have been studied. The problems of laser radiation propagation and distribution of temperature field in the tips are considered. The radiation transfer equation is solved for axial symmetric semi-transparent bodies by methods of statistical modeling with linear optics approximation in unscattering medium. The distribution of radiation intensity is obtained at the tip exits by statistical analysis. It is shown that the main thermal source is the absorption of laser radiation on the surface of the tip. The energy equation is solved for real instruments by finite-difference methods, taking into account the nonlinear transport coefficients.
