Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...

Iterative Curve Fitting: A Robust Technique To Estimate The Wavelength Position And Depth Of Absorption Features From Spectral Data
(IEEE-Inst Electrical Electronics Engineers INCPiscataway, 2016)
Comparison of different Aethalometer correction schemes and a reference multi-wavelength absorption technique for ambient aerosol data
(Copernicus Gesellschaft Mbh, 2017)
Deriving absorption coefficients from Aethalometer attenuation data requires different corrections to compensate for artifacts related to filter-loading effects, scattering by filter fibers, and scattering by aerosol ...
Soot pyrometry by emission measurements at different wavelengths in laminar axisymmetric flames
(Taylor and Francis, 2020)
In this work, a multi-wavelength pyrometry method is proposed in order to evaluate soot temperature for laminar axisymmetric non-premixed flames. A single radiative model that combines three detection wavelengths is developed ...
Tunable plasmon resonance modes on gold nanoparticles in Er 3 +-doped germanium-tellurite glass
(2013-08-05)
Relative to the Er3 +:gold-nanoparticle (Er3 +:Au-NP) axis, the polarization of the gold nanoparticle can be longitudinal (electric dipole parallel to the Er3 +:Au-NP axis) or transverse (electric dipole perpendicular to ...

Dynamics of energy transfer and frequency upconversion in Tm3+ doped fluoroindate glass
(2004-09-01)
The spectroscopic properties of Tm3+-doped fluoroindate glasses (FIG) were described by single wavelength pumping in the red region. The Judd-Ofelt (J-O) theory was used to obtain the quantum efficiency of the 4f-4f ...
