During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

At-home laser hair removal devices have been popular for their convenience, safety, relative comfort and results. If you’re curious about trying one out yourself, you may be wondering if the portable ...

An incredible image buried deep in an annual military report released last month shows the U.S. Navy test-firing a high-powered laser weapon at a drone target from one of its warships. The photo of ...

As someone with pitch-black, thick body hair that seems to regrow within hours of shaving, I’ve always been tempted to bite the bullet and try laser hair removal. The idea of a semipermanent, ...

Prototype quantum photonic-dimer laser uses entanglement to bind photons and deliver a powerful beam of concentrated light that can shine through adverse weather like thick fog. When you purchase ...

The age of the laser weapon is finally upon us. The United States Army has officially sent a pair of high-energy laser weapons overseas to defend American troops and US allies against enemy drones, ...

After decades of research and development, the U.S. military is officially using laser weapons in combat zones overseas. The U.S. Army recently disclosed that the service had not only deployed a pair ...

Every item on this page was chosen by an ELLE editor. We may earn commission on some of the items you choose to buy. We love a high-tech skin care device around these parts. A light therapy device for ...

A tiny, levitated bead is at the core of an unprecedentedly bright laser that shoots particles of sound instead of light. Just as a ray of light is made up of many particles called photons, sound ...

The Army has inked a contract with defense giant Lockheed Martin for a platoon's worth of what would be the U.S. military's most powerful laser weapon system to date, the company announced Tuesday.
