Based on nonlinear optical properties test of materials,the basic principles of the primitive Z-scan techniques and data processing are firstly introduced in this paper,and then technical theories of the two-color time-resolved Z-scan technology are discussed emphatically,as well as its superiority in the material optics non-linear effect test and some questions ought to pay attention to.

The optical nonlinear properties of BTN-SubPc spin-coating films were measured by means of Z-scan technique using a mode-locked Nd∶YAG laser with 38 ps pulse excitation at 1.

0 nm were investigated by the Z-scan technique.

The paper describes optical limiting properties of a new Nickel complexes were investigated by the Z-scan technique.

With nanosecond pulses at 532 nm wavelength, firstly the nonlinear optical absorption and refraction coefficients of Ni(mpo)2 complexs by using the Z-scan technique was measured.

Optical absorption spectrascopy and Z-scan technique were used to measure linear absorption and third-order optical nonlinearity of the films.

Studies on the Mid-infrared Photon Localization in Random Media and the Z-scan Technique;

The Z-scan technique is a very important yet simple method for characterizing the optical nonlinearities, and can measure the magnitudes and signs of the imaginary (Im[χ~(3)]) and real (Re[χ~(3)]) parts of third-order susceptibility (χ~(3)) simultaneously.

A new dynamic experimental technique, the time resolved reaction chromatography technique (TRRCT), has been developed to obtain the elution curves of time-concentration for the reactants after passing the reaction column.
