A new method could improve cosmology research by analyzing supernovae together with the galaxies that host them.

Abstract: Conventional detection scheme for self-mixing sensors uses an integrated photodiode within the laser package to monitor the self mixing signal. This arrangement can be simplified by directly ...

The U.S.military is paving the way for the regular deployment of high-energy laser weapons on American soil for air defense amid the expanding threat of low-cost weaponized drones. The Federal ...

The U.S. government can now use a counterdrone laser along the southern border after the Pentagon and Federal Aviation Administration (FAA) agreed the weapons are safe, the two agencies announced ...

Military and aviation safety officials have finished a safety assessment of the use of lasers to counter drones along the U.S. border with Mexico and found a way to move forward that will keep air ...

The Federal Aviation Administration and Pentagon said on Friday they had signed an agreement allowing the government’s use of a high-energy laser counter-drone system along the southern U.S. border ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in ...

Laser weapons are such an entrenched sci-fi trope that it's easy to forget just how real this tech can be (and is). While we're not exactly close to seeing real-life "Star Wars" space battles, the U.S ...

Abstract: The error field plays an essential role in improving the positioning accuracy of the distributed measurement system (DMS). The key is to identify and ...

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 ...
