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 ...

There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor ...

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 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 ...
