Dual-Criteria Decision Analysis by Multiphotonic Effects in Nanostructured ZnO

Micromachines
Simultaneous interrogation of pump and probe beams interacting in ZnO nanostructures of a two-wave mixing is proposed for dual-path data processing of optical signals by nonlinear optical effects.

Autowaves in moving excitable media

Condensed Matter Physics, 2004
Within the framework of kinematic theory of autowaves we suggest a method for analytic description of stationary autowave structures appearing at the boundary between the moving and fixed excitable media.

Nonlinear Refraction Traveltime Tomography [PDF]

, 1996
We identify a few unique issues that are important for performing a nonlinear refraction traveltime tomography effectively. These include accuracy of traveltime and raypath calculation for a turning ray and physical information in a refraction ...

Direct Measurements Of Nonlinear Absorption And Refraction In Solutions Of Phthalocyanines

, 1992
We report direct measurements of the excited singlet state absorption cross section and the associated nonlinear refractive cross section using picosecond pulses at 532 nm in solutions of phthalocyanine and naphthalocyanine dyes.

Efficient Tuning of the Third-Order Nonlinear Optical Properties of Some Functionalized Boron-Dipyrromethene Dyes

Nanomaterials
In the present work, the third-order nonlinear optical (NLO) response of some recently synthesized, functionally substituted Boron–Dipyrromethene (BODIPY) derivatives is studied, and their nonlinear optical properties are investigated using the Z-scan ...

Nonlinear Refraction of Semiconductor Quantum Dots Using Single Wavelength and White-Light Continuum Z-scan

, 2007
The nonlinear refractive index is measured in semiconductor quantum-dots using white light continuum Z-scan, which can measure nonlinear refraction as small as 10-16cm2/GW. The magnitude of the nonlinearity decreases for smaller quantum-dots.

Spectral Measurement of Nonlinear Absorption and Refraction Using a White-Light Continuum Z-scan

, 2005
We use a white-light continuum (WLC) as the source in a standard Z-scan technique to measure the degenerate two-photon absorption (2PA) spectrum and the nonlinear refraction dispersion in optical materials.
