Scientists agree that laser beam tests in uncontrolled conditions, especially over water, are not a reliable means to prove the Earth's shape due to atmospheric refraction.

The researchers ran a laser in “doughnut mode,” where the beam has a hollowed-out core along its length, resembling a stack of luminous doughnuts. The beam creates a hot, tubular air layer ...

Physicists make laser beams visible in vacuum Date: August 25, 2021 Source: University of Bonn Summary: A beam of light can only be seen when it hits matter particles and is scattered or reflected ...

Laser Beam Sends Electricity Nearly 100 Feet Through the Air Published Sep 02, 2022 at 11:53 AM EDT Updated Sep 02, 2022 at 1:39 PM EDT By Jess Thomson ...

In contrast, Iron Beam is an optical fiber laser that can lock onto targets at the speed of light and destroy them within five seconds at a range of up to 7 km (4.3 miles).

Iron Beam M fires a 250 mm. 50 kW beam and can be mounted on large trucks for mobility but cannot be placed as a minor additional system on individual vehicles.
