Third-order optical nonlinearities of Cu and Tb nanoparticles in SrTiO_3

摘要

Some results of optical and nonlinear-optical properties of Cu and Tb nanoparticles implanted in SrTiO_3 (STO) crystal are presented. The non-resonant third-order optical nonlinearities have been investigated by degenerate four wave mixing (DFWM), pump-probe and Z-scan techniques using femtosecond laser pulses.
