Nonlinear refractive index of optical crystals
Physical Review B, 1989The nonlinear refractive indices (${n}_{2}$) of a large number of optical crystals have been measured at a wavelength near one micrometer with use of nearly degenerate three-wave mixing. The measurements are compared with the predictions of an empirical formula derived by Boling, Glass, and Owyoung.

Dispersion of the nonlinear refractive index in sapphire
Optics Letters, 2004The nonlinear refractive index, n2, of sapphire was experimentally measured in the 550-1550-nm wavelength range by use of a picosecond Z-scan technique. It was found that in this spectral region the value of n2 decreases monotonically from approximately 3.3 x 10(-16) to approximately 2.8 x 10(-16) cm2/W.

Nonlinear Refraction and Nonlinear Absorption in InAs
1984We report here experimental measurements taken with an HF laser of a large nonlinear index of refraction (n2 = 4.5 ± 2.0 × 10-5 cm2/W) and associated nonlinear absorption near the bandgap in InAs between 6°K and 100°K. These results are shown to be consistent with the bandgap resonant model used to explain the nonlinearities seen in InSb and HgCdTe ...

Nonlinear refractive index of solids in mid-infrared
Optics Letters, 2021We measure the third-order nonlinear optical response of various dielectrics and semiconductors using the spectrally resolved two-beam coupling method at 2.3 µm, 3.5 µm, 4.5 µm, and 8.3 µm. These materials include fused silica, sapphire, calcium fluoride, magnesium fluoride, zinc sulphide, and zinc selenide.

Nonlinear refractive index of photo-thermo-refractive glass
Optical Materials, 2006Abstract Nonlinear properties of a photo-thermo-refractive (PTR) glass are studied and compared with those in fused silica and a conventional optical glass. PTR glass is a new photosensitive medium for high-efficiency phase volume hologram recording which manifests a linear refractive index modulation after exposure to UV radiation followed by ...

Ultrafast dynamics of nonlinear refraction
Latin America Optics and Photonics Conference, 2018We introduce the nonlinear beam deflection technique that allows unambiguous separation of slow and fast nonlinearities. This highly sensitive method allowed characterization of a wide range of materials, including solvents, gases, semiconductors and transparent conducting oxides.

Nonlinear index of refraction in semiconductors
Il Nuovo Cimento D, 1984Experimental work on light refraction in semiconductors suggests that there are two separate mechanisms by which the index of refraction becomes nonlinear: direct saturation, on the one hand, and the Burstein-Moss effect, on the other hand. We show that this picture is incorrect, since it was based on the usage of the Bloch equation.

The nonlinear refractive index of glass
IEEE Journal of Quantum Electronics, 1974The general theory of the third-order electronic susceptibility has been specialized to some model systems in order to evaluate the associated nonlinear refractive index of solid materials. The results indicate oppositely signed terms of comparable magnitude, and it is found that the dominant positive contribution involves oscillator strengths ...

Nonlinear spectroscopy: absorption and refraction
SPIE Proceedings, 2009We have been developing tools for nonlinear spectroscopy aimed toward the ultimate goal of building a nonlinear spectrophotometer analogous to the ubiquitous linear spectrophotometer where a sample is placed in the instrument, a button is pushed, and the absorption spectrum is obtained sometime later.

Nonlinear-optical energy regulation by nonlinear refraction and absorption in silicon
Optics Letters, 1984We demonstrate a new silicon picosecond nonlinear-optical energy regulator for 1-microm radiation. The device has a high transmission for low input energies and a low transmission for high input energies and clamps the output at a constant value. We attribute this optical Zener action to nonlinear refraction and absorption induced in the silicon by the
