In 1987, the physicists Hong, Ou and Mandel observed the behavior of photon pairs in a beam splitter in an experiment that until recently had been independent of topology. They discovered that a ...

Photon profilers analyze beam parameters, including the beam's profile, size, position, and M² of lasers and optics in manufacturing and R&D. People come to us because they trust Photon to help with ...

As two-photon processes are nonlinear and require high-optical intensities to occur, they typically only take place at the focal spot of a light beam. This characteristic offers the ability to ...
