Coherent beam combining (CBC) in fiber laser systems is an innovative approach that enhances the output power and efficiency of laser systems by combining multiple laser beams into a single ...

In 2024, seven vehicles in western China each transmitted a high-powered microwave beam that converged precisely in both time ...

Spatial coherence means that there is a well-defined beam with well-defined phase across it. For many lasers, the divergence of the laser beam is as low as 1–2 times the diffraction limit ...

Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To ...

By combining the National Ignition Facility (NIF) laser and ultra-light metal foams, researchers at Lawrence Livermore ...

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It's a goal that sounds so fantastic, you'd be forgiven ...

Another benefit is the higher power output. Multimode laser diodes are able to generate higher optical power, making them ...

Just a short distance outside of Fort Collins on the Colorado State University Foothills Campus sits one of the most powerful ...

Rafael presented its Lite Beam and Iron Beam high-energy lasers (HELs) at Defence iQ's International Armoured Vehicles (IAV) ...

and the stimulated photons bounce back and forth between the mirrors until some finally blast out through the partial mirror to form a coherent, monochromatic laser beam. By contrast, an open ...
