Scientists have long used Gaussian beams to study how light interacts with matter. These beams resemble plane waves and rely ...

A major scientific breakthrough could change how we understand and control ionization — the process where atoms lose electrons and become charged. Researchers from the University of Ottawa have ...

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their ...

Try to fathom the power of 1 million nuclear power plants. Now, imagine there is a way to pack the equivalent of that into ...

Cheap drones are exposing gaps in current air defense systems, and countries in the Middle East are looking to laser weapons ...

Intense beams of laser light interact with crystals to yield novel optical effects. For example, when two beams meet in a crystal they can add or subtract to produce beams of two new wavelengths ...

However, for many other applications, especially those requiring intense laser light — such as marking or cutting metals — they are simply not up to task. The chief problem is their poor beam ...

DLW is an additive manufacturing technique that uses a focused laser beam to selectively solidify ... features—is difficult because the intense laser light can cause unwanted exposure in ...
