Nonlinear photoacoustics for measuring the nonlinear optical absorption coefficient [PDF]
Optics Express, 2010 We report a novel photoacoustic Z-scan (PAZ-scan) technique that combines the advantages offered by the conventional Z-scan method and the sensitivity of the photoacoustic detection.

Journal of Functional Analysis, 1993 Let \(A\) be an \(m\)-completely accretive operator in \(L^ 1(\Omega)\), where \((\Omega,{\mathcal B},\mu)\) is a \(\sigma\)-finite measure space. Let \(j: \Omega\times\mathbb{R}\to [0,\infty]\) be measurable in \(x\in\Omega\), convex and lower semicontinuous in \(r\in\mathbb{R}\), with \(j(x,0)=0\).

Wavelength-Dependent Nonlinear Absorption in Palladium Nanoparticles
Applied Sciences, 2021 This paper aims to study the nonlinear absorption characteristics of palladium nanoparticles (PdNPs) at off-resonant wavelengths. For this purpose, multi-wavelength (500–650 nm) nanosecond Z-scan technique was used. The experimental results indicate that

Nonlinear Absorption Microscopy† [PDF]
Photochemistry and Photobiology, 2009 AbstractFor the past two decades, nonlinear microscopy has been developed to overcome the scattering problem in thick tissue imaging. Owing to its increased imaging depth and high spatial resolution, nonlinear microscopy becomes the first choice for imaging living tissues. The use of nonlinear optical effects not only facilitates the signal originating
