✦ Synopsis

Processes of laser interaction with metal (gold)
nanoparticles are of great interest for laser applications in
nanotechnology, engineering, and medicine. Optical properties of
nanoparticles determine photophysical and photochemical processes
during laser treatment. Computer calculation of efficiency factors
of absorption, scattering and extinction of radiation by
ellipsoidal gold nanoparticles (two-dimensional ellipsoids of
revolution) with small semiaxes in the range 5–100 nm, for some
values of aspect ratio and angle of orientation of ellipsoid with
respect to direction of laser radiation propagation and for some
laser wavelengths is performed. The estimation of absorbed and
scattered laser radiation energy by gold ellipsoidal
nanoparticles, their maximal temperatures and comparison with
experimental data is made.
