Coherent light is produced by a beam of photons that all have the same frequency and are all at the same phase. And today lasers are the only form of technology that we know able to create such light.

Analytical optical methods are vital to our modern society as they permit the fast and secure identification of substances within solids, liquids or gases. These methods rely on light interacting with ...

A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top x-ray sources. A new way of producing coherent light in the ...

Coherent extreme ultraviolet (XUV) and soft x-ray radiation are very powerful in studying various material properties in biology, chemistry, and physics. Synchrotron radiation (SR) and X-ray free ...
