Since the advent of lasers, researchers have strived to build an acoustic equivalent — devices that can amplify and emit sound waves at a single frequency. Kerry Vahala and his group at the California ...

Laser beams are usually hard to miss, but a new laser is notable for its lack of light. Steven Cundiff at the University of Colorado in Boulder and his colleagues built the device by modifying a ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
