The control of luminous radiation has extremely important implications for modern and future
technologies as well as in medicine. In this Review, we detail chemical structures and their …

Optical nonlinearity in 2D materials excited by spatial Gaussian laser beam is a novel and
peculiar optical phenomenon, which exhibits many novel and interesting applications in …

Large two-photon absorptivities are reported for symmetrical bis-donor stilbene derivatives
with dialkylamino or diphenylamino groups. These molecules exhibit strong optical limiting …

There is considerable interest in finding materials having large yet fast nonlinearities. This
interest, driven primarily by the search for materials for all-optical switching and sensor …

The features of the closed-aperture (CA) Z-scan transmittance curves have been studied in
detail when the third-order nonlinear refraction and absorption, both of which can be …

Having accomplished progress in the versatile battlefields of optics, electronics, catalysis,
etc., two-dimensional (2D) materials are now venturing and excelling in yet another arena of …

The nonlinear optical response of a series of azo-containing side-chain polymers is
investigated using Z-scan technique, employing 35ps and 4ns laser pulses, at 532 nm. The …

The third-order nonlinear optical properties of Basic Green 1 dye were measured by the Z-
scan technique and measurements were carried out at different concentrations and several …

A modification to the well-known z-scan technique for measuring optical non-linearities is
introduced. It is based on directly measuring the beam radius in the far field instead of the …

We review Z-scan and related techniques for the measurement of the nonlinear optical
properties of materials. The Z-scan is a simple technique for measuring the change in phase …
