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, ...

Nonlinear spectra of ZnO: reverse saturable, two- and three-photon absorption
(OPTICAL SOC AMER, 2010)
We present a broadband (460-980 nm) analysis of the nonlinear absorption processes in bulk ZnO, a large-bandgap material with potential blue-to-UV photonic device applications. Using an optical parametric amplifier we ...
Control of nonlinear absorption and amplification of light in Er3+-doped fluoroindate glass
(1999-11-01)
Nonlinear absorption and amplification of a probe laser beam can be controlled by adjustment of the intensity-modulation frequency and the wavelength of a pump laser beam. A demonstration of this effect in Er3+-doped ...

The effect of bulk light absorption on running photorefractive holograms
(Iop Publishing Ltd, 2000-01-01)
The influence of bulk light absorption on running photorefractive holograms is investigated. By solving the coupled wave equations we prove that the beam intensities, but not the beam phases, can be calculated by averaging ...
