Abstract
Theoretical investigation is carried out of the heating of a small solid (metal) ellipsoidal particle in a liquid or gaseous medium by laser radiation pulses. The solutions are obtained for quasi-stationary distributions of temperature inside and around of a particle and conductive heat transfer between the particle and the surrounding medium with allowance for the temperature dependence of the transfer coefficients. The heating of ellipsoidal nanoparticle in medium on exposure to laser radiation pulse and following cooling is considered on the base of analytical solutions. The time dependencies of particle temperature are obtained. The estimation of absorbed and scattered laser radiation energies by gold ellipsoidal nanoparticles, their maximal temperatures and comparison with experimental data is made.Keywords
