摘要：
The electrostrictive orientational mechanism of optical nonlinearity in the artificial Kerr-like medium with nonspheroidal nanoparticles is analyzed. The thermal contribution to the cubic nonlinearity of transparent nanosuspension takes into account for the first time. The exact solution was obtained for the light induced lens response in a one-beam scheme. It is shown that thermal response reduces the value of electrostrictive nonlinearity for the shot time period and disappears in the stationary state.
