Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

We describe an unsaturated gain–loss model in regards to colloidal PbSe quantum dot (QD)-doped fiber laser realized previously. Based on experimental observation on the laser, the numerical simulation ...

Abstract: This paper presents the investigation of non-linear mirror (NLM) modelocking of a bounce amplifier laser. In this technique, the combination of an intracavity second harmonic generation ...

UC Irvine professor of ophthalmology and biomedical engineering Tibor Juhasz spent 25 years perfecting a laser treatment for ...

One of those investigations involved a distinctive deep dive into studying the interior of the moon.

UF engineers, backed by DARPA and NASA, are perfecting laser-forming techniques that let metal sheets fold themselves into giant solar arrays, antennas, and even space-station parts right in ...

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Carbon, one of the most abundant elements in the universe, constitutes many key components of life and technology. Because of this, the material is ...

Physicists at the University of Oxford have unveiled a “pioneering” method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, a collaboration ...
