Applied physics bridges the gap between physics, engineering, and other sciences. While engineers solve well-defined problems, applied physicists focus on applying physics interdisciplinarily. At ...

New ground-breaking research could change the way scientists understand and describe lasers - establishing a new relationship between classical and quantum physics. New ground-breaking research from ...

The development of laser effectors at the Institute of Technical Physics focuses on optimising the beam quality of high power lasers in continuous wave or pulsed operation and their power scaling into ...

Scientists are using an adapted version of VPIC, a particle-in-cell plasma physics code, to model the nonlinear physics of laser backscatter energy transfer and plasma instabilities in an attempt to ...

ROCHESTER, NY AND TUCSON, AZ / ACCESS Newswire / June 10, 2025 / Applied Energetics, Inc. (OTCQB:AERG) (AE), a leader in ultrashort pulse directed energy and laser, is pleased to announce it has been ...

Integrated laser platform: A single chip generates narrow linewidth and tuneable visible light covering all colours. (Courtesy: Myles Marshall/Columbia Engineering) Researchers in the US have created ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. A bit over 25 years ago ago, probably late 1991 or very early 1992, ...

The detection and removal of space debris contributes to the preservation of space as a usable infrastructure. In the future, efficient and cost-effective solutions based on observation networks will ...

Scientists Arthur Ashkin, Gerard Mourou and Donna Strickland have won the 2018 Nobel Prize for Physics for breakthroughs in the field of lasers used for surgery as well as scientific study. Arthur ...
