The nature of discovered by us for the first time phenomena of nonstationary surface plasmon frequency and their polarization splitting in spherically-shaped copper nanoparticles in transparent isotropic matrices in the field of powerful femtosecond laser pulses (~10^12 W/cm2) has been investigated. It has been shown that induced dynamic anisotropy of refractive index of the matrix is the origin of the phenomena. The anisotropy appears due to the influence of nonlinear-optical effects, which accompany the process of propagation of powerful laser pulses in a transparent isotropic media (glasses of different nature): optical Kerr effect, multi-photon absorption and ionization of the substance with the appearance of two-component plasma, filamentation phenomena (separation of solid light flow into separate discrete treks of micron thickness). Time gate of the above nonlinear-optical phenomena and their contribution into surface plasmon dynamics have been determined. For the fist time, the possibility of micro-waveguides recording induced by filaments has been shown, that can be used in nanophotonic device development.
