“For any coherent light source that you want to move to a different wavelength, you need a nonlinear crystal,” he says. Probably the biggest seller, in his opinion, is lithium ...

The study of nonlinear propagation in optical fibres dates back to the early 1970s and the first fabrication of low-loss silica fibre waveguides. Nonlinearity in fibres arises primarily from the ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

Chirality refers to objects that cannot be superimposed onto their mirror images through any combination of rotations or ...

Chirality is the property of an object that makes it different from its mirror image, like our left and right hands. In ...

1. Femtosecond pulses from the fs pump laser are passed through a second-order nonlinear crystal. Once the threshold for OPG is reached, the pump pulses are converted into signal and idler pulses with ...

Rather, as optics aficionado [Les Wright] explains, non-linear optics is all about physics ... and everything is allowed to cool slowly. A nice seed crystal is glued to a piece of monofilament ...

MicroCloud Hologram Inc. (NASDAQ: HOLO), ("HOLO" or the "Company"), today announced the development and application of Quantum Nonlinear Optical Holography (QNOH) technology to directly generate ...

In this process, a single high-energy photon enters a nonlinear optical medium (such as a BBO crystal) and, through interaction with the crystal, splits into two lower-energy photons, which are ...

Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other ...
