✦ Synopsis
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.
