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 ...

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 ...

Hobbyist 3D printers have had a home in the maker space for years now. Along the way, they’ve left a mark in our imaginations. They’ve tickled our fancy for watching a computer orchestrated symphony ...

A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand. Published in APL Photonics, the technique offers a promising route ...
