Flashes of femtosecond laser light, lasting just a few trillionths of a second, have made it possible to observe new magnetic ...

Researchers showed how combining twisted light and frequency combs together can produce an even more novel structure of light. It is not every day that scientists are able to produce an entirely new ...

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 intense ...
