A Nature study shows bright squeezed vacuum can drive nonlinear laser interactions far more efficiently, reducing the need for destructive intensity levels.

U.S. Navy leaders are again making the case for directed-energy weapons, but their own testimony shows the central obstacle has not changed: current surface ships still struggle to provide the power and cooling laser war

Researchers at the University of Virginia say a continuous-wave infrared laser can remove backsheets from end-of-life silicon solar modules without damaging glass or wafers, pointing to a lower-energy recycling approach.

Researchers at Texas A&M have demonstrated microscopic devices that can be lifted and steered in three dimensions using only laser light, a lab result that could strengthen long-term efforts toward laser-driven inter

Two highly precise hydrogen experiments now agree with the smaller proton measurement that once shocked physics, strengthening the case that the particle’s radius is about 0.84 femtometres.

A new quantum racetrack laser design could shrink spectrometer functions from laboratory systems down to microchip-scale devices.
