Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS devices typically have actively moving ...

Smoke rose from a drone after it was shot down by a 50-kW laser mounted on a U.S. Army Stryker vehicle. Credit: U.S. Army High-energy lasers are having a long-overdue moment. Two incidents in late ...

There are plenty of ways to remove unwanted body hair: shave, wax, epilate. But if you’re looking for a more permanent result, laser hair removal is the way to go. The only downside? In-office ...

Ukraine has developed a silent, undetectable laser that can take out Russian drones as if “struck by invisible lightning” — and all at a fraction of the cost of similar high-tech weapons made in the ...

After facing possible steep budget cuts that could have shut down a Louisiana space observatory, scientists are breathing a sigh of relief after recently approved federal science funding exceeded ...

Common to optical metrology in many modern systems, the Fizeau design uses a fixed, on-axis coherent point source to illuminate the interferometric cavity. For the most part, it works very well. While ...

The future arrived on December 28, 2025 as the Israeli Defense Force (IDF) announced that Iron Beam became the first high-energy tactical laser weapon to be fully integrated and cleared for operations ...

We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a very small number ...

FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power. By using custom thermal patterns, it preserves mirror shape without ...

A quadcopter drone burns after being hit by a laser weapon system at Camp Roberts, California, Feb. 6, 2025. (Dan Linehan/U.S. Navy) The U.S. Army aims to produce up to 20 high-energy laser weapons to ...
