Mid-infrared Kerr index evaluation via cross-phase modulation with a near-infrared probe beam
Dusan Lorenc, Zhanybek Alpichshev
We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared frequency range that avoids using sophisticated infrared detectors. Our approach is based on u…
