Z-scan and four-wave mixing characterization of semiconductor cadmium chalcogenide nanomaterials

Self-diffraction and high nonlinear optical properties of carbon nanotubes under CW and pulsed laser illumination

“…In other parts, the nonlinear absorption of nano-suspension was measured. Several different experimental methods can be employed to measure TPA coefficients such us converted fluorescence emission [11], transient absorption [12], four-wave mixing [13] and the z-scan technique [14,15]. Among these methods, the z-scan technique, which was first introduced by Sheik-Bahae et al in 1989 [16], is a particular example.…”
