Modified Z-scan techniques for investigations of nonlinear chiroptical effects

open access: yesOptics Express, 2004
We present simple modifications of the classic Z-scan technique for the investigations of nonlinear chiroptical effects, i.e. nonlinear circular birefringence and two-photon circular dichroism. Two methods for studying these effects: a "polarimetric Z-scan" and a "polarization modulated Zscan" are described in detail.

Effect of temperature on the structural, linear, and nonlinear optical properties of MgO-doped graphene oxide nanocomposites

open access: yesNanophotonics, 2018
Magnesium oxide (MgO)-graphene oxide (GO) nanocomposites were prepared by the hydrothermal method at different temperatures. The effect of growth temperature on the structural, linear, and nonlinear optical (NLO) parameters was investigated.
