Distributions of laser radiation intensity inside gold nanoparticles during laser irradiation

Theoretical investigation of the distributions of laser radiation intensities inside spherical gold nanoparticles with radiuses in the range 5-100 nm during laser irradiation for wavelengths 400, 532, 800 nm was carried out. Distributions of laser intensity are nonhomogeneous for some ranges of nanoparticle sizes and values of laser wavelengths. These results can be applied for explanation of some experimental data of laser-induced fragmentation, evaporation and formation of nanonetworks as a result of laser action on nanoparticles and for laser technologies of nanoparticles.
