Like artists, scientists use color to paint clearer pictures of the things -- everything from combustion gases to cancer cells -- they study. And as a result of a new laser system that rapidly ...

These phase fluctuations create "noise" in the laser spectrum—they smudge the laser's frequency, making it less pure in color. The Raman technique works by transferring these timing irregularities ...

A laser that changes colour when it stretches has been developed by a team of scientists from Germany and the US. Heino Finkelmann of Albert-Ludwigs University in Freiburg, Germany, and co-workers ...

Fiber lasers are now well-developed and reliable devices used in a wide range of applications. As it occurs with other types of cavity resonators, the confinement of light within the optical cavity of ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand – a discovery that could revolutionise quantum ...

In another step forward for laser weapons that brings to mind the Death Star's superlaser, Lockheed Martin has demonstrated a 30-kilowatt fiber laser produced by combining many lasers into a single ...

The "world's first source of truly broadband power" generates high-brightness output from the deep ultraviolet to the visible range and beyond. Energetiq Technology, a US-based developer of ...
