Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy — a specialized imaging technique that looks for a change in the color of ...

Nonlinear optics is the branch of photonics that studies material responses wherein the induced polarisation is not directly proportional to the applied electromagnetic field. In these media, intense ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.210006 overviews expanding infrared microspectroscopy with the Lucy-Richardson-Rosen computational reconstruction method.

Here’s an exercise for you: type “crystals” into your favorite search engine and see what you get. If you’re anything like us, you’ll get a bunch of pseudoscientific posts about the healing power of ...

Professor Edmund Lam, Dr. Ni Chen and their research team from the Department of Electrical and Electronic Engineering under the Faculty of Engineering at the University of Hong Kong (HKU) have ...
