Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...

A team of researchers at Bar-Ilan University has found a way to use correlated photons to make sharper X-ray images. In their paper published in the journal Physical Review Letters, the group describes their process and suggest ...
In order to evaluate a material's ability to withstand the high-radiation environment inside a nuclear reactor, researchers have traditionally used a method known as "cook and look," meaning the material is exposed to high ...
