Lasers

A spacecraft destined to explore a unique asteroid will also test new communication hardware that uses lasers instead of radio waves.

How do lasers work?

The scientists used lasers and magnets.

My dream was so cool! There were lasers, and there were robots, and there was fire, and—why aren’t you listening?

Using infrared lasers, LCRD will send data to Earth from geosynchronous orbit at 1.2 gigabits-per-second (Gbps). At this speed and distance, you could download a movie in under a minute.

Scientists from the Lawrence Livermore National Laboratory report they were able to create a type of fusion reaction by bombarding a microscopic pellet of fuel with beams from 192 powerful lasers to compress its component parts — hydrogen isotopes known as deuterium and tritium — and fuse them together at the atomic level.

From lasers that cut denim at a factory, to drones that irrigate crops, it’s not a new story that machines are doing more work than ever.

"Ziri was shooting lasers at us." "Ignore him."

Bruno started shooting out lasers.

Lasers have made measurement an exact science. Astronomers have used lasers to measure the moon’s distance from Earth to within a few centimeters. Mappers and builders use laser technology every day. For example, drawing a perfectly level straight line on a construction site is easy using a laser.
