Thulium fiber lasers, operating at a wavelength of 2 μm, are valued for applications in medicine, materials processing, and defense. Their longer wavelength makes stray light less damaging compared to ...

Cladding light stripper (CLS) technology addresses a major challenge in scaling thulium fiber lasers beyond their long-standing 1 kW power limit. A new self-adapting CLS design distributes heat along ...

Producing the subatomic particles called muons is now a lighter lift than ever before. Several teams of researchers have generated muons using small particle accelerators driven by lasers. Typically, ...

The week’s best and worst from Mene Ukueberuwa, Allysia Finley and Kyle Peterson Don’t call it “Star Wars.” Israel’s Iron Beam laser air-defense system was declared operational Wednesday after final ...

Australian defense company Electro Optic Systems (EOS) has unveiled its Apollo High Energy Laser Weapon (HELW) that pumps out up to 150 kW of power yet can take out 200 medium-sized drones running on ...

Scientists at Michigan State University have discovered how to use ultrafast lasers to wiggle atoms in exotic materials, temporarily altering their electronic behavior. By combining cutting-edge ...

For a while missiles looked like potential prey. They have thin skins and are packed with fuel and explosives. Merely damaging the shell of a supersonic missile can create drag, causing it to tumble ...

You can now order an “Iron Dome” for mosquitoes. Its name is the Photon Matrix, a black box about the size of a smartphone that can detect, track, and eliminate mosquitoes mid-flight using an ...

Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works at room temperature, using a buried layer of glass-like material instead of ...
