INVESTIGATION OF THE NONLINEAR INDEX OF REFRACTION OF WATER AT 815 AND 407 NANOMETERS
… window. The technique was used to measure the nonlinear index of refraction due to the optical Kerr effect in water at both 815 nm and 407 nm with pump pulse lengths of ~90 femtoseconds and ~250 femtoseconds respectively. The 815 nm measurement serves as a benchmark against previous published …

The Development of a Novel Femtosecond Xuv Light Source to Do Spectroscopy of Atoms and Molecules.
… and/or dissociate a molecular medium. The static index of refraction of the medium, which represents the medium response to a weak field, is no longer valid for describing the response to a strong field. The dynamic nonlinear index of refraction depends very strongly on the intensity of the …

All-optical interferometric switches for data regeneration in fiber optic networks
In the thirty years since the installation of the first fiber optic data link, data rates in installed fiber links have risen from a few Mb/s to tens of Gb/s. In the laboratory, data rates in a single optical fiber have already reached tens of Tb/s. These data rates greatly exceed electronic …

Measurement of the nonlinear refractive index (n2) and stimulated Raman scattering in optical fibers as a function of germania content, using the photorefractive beam coupling technique
One of the greatest challenges in optical communication is the understanding and control of optical fiber nonlinearities. While these nonlinearites limit the power handling capacity of optical fibers and can cause noise, signal distortion and cross talk in optically amplified transmission systems, …
