Caltech scientists are developing laser-driven lightsails that could push spacecraft beyond our solar system. Their research ...

MKS Instruments, Inc., a global provider of enabling technologies that transform our world, has announced the Ophir® BeamSquared® SP204S-PRO and Ophir® BeamSquared® SP1203 M2 beam propagation ...

For centuries, space travel has been limited by traditional propulsion methods, with chemical rockets remaining the primary ...

Abstract: A novel technique is proposed for estimating the angle-of-arrival (AOA) in free-space laser communication based on the shape of a laser beam spot on a flat surface. Two methods are ...

Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called photons. Notable examples include laser-powered ...

TAU Systems is developing laser-plasma accelerators to simulate cosmic rays and accelerate testing of electronics for deep ...

The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," he said. "At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays ...

US president orders work on defence shield going beyond Ronald Reagan’s ‘Star Wars’ programme that could trigger nuclear arms ...

That’s where LiDAR comes in. Like radar, but using light, LiDAR sends beams from a plane or satellite towards the ground. By measuring the time it takes for the light to be reflected, scientists can ...

The M4A1 is one of, if not the strongest, weapon in Delta Force for Operations and Warfare. Boasting excellent range, fire ...

In every toolbox, there should be an instrument that helps you achieve level surfaces and wall hangings. This is that tool, ...
