The new technique is the first of its kind that’s safe to use around humans
An MIT study proposes that laser technology on Earth could emit a beacon strong enough to attract attention from as far as 20,000 light years away.
A fast-pulsing beam creates a tiny shock wave to dispel water droplets in the air
A billion operations per second isn’t cool. Know what’s cool? A million billion operations per second.
The maser (microwave amplification by stimulated emission of radiation), the older microwave frequency sibling of the laser, was invented in 1954. However unlike lasers, which have become widespread, masers are much less widely used because in order to function they must be cooled to temperatures close to absolute zero (-273°C).
A large team of Russian researchers from Rosatom, joined by three MIPT physicists, has modeled the impact of a nuclear explosion on an Earth-threatening asteroid.
A design based on exotic materials lets scientists better control the flow of light particles
A spacecraft destined to explore a unique asteroid will also test new communication hardware that uses lasers instead of radio waves.
The silk proteins themselves are involved in locally increasing the laser power.
