He also used the laser to melt through tungsten, an ultra-strong metal with a melting point of 3,422 degrees Celsius, which is the highest melting point of any metal. He even set a diamond on fire.

The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry ...

Now there’s a laser vape. Meet Luminary’s The Beam, a handheld, pocket-sized vaporizer that uses a class-1 laser you can actually see to heat weed extracts. I thought for sure it was a gimmick.

Try to fathom the power of 1 million nuclear power plants. Now, imagine there is a way to pack the equivalent of that into the pulse of a laser beam—even if it’s only for one quadrillionth of ...

“We have demonstrated the method by printing 120-nanometer-resolution structures using a low-cost diode laser,” Pan said. “We also demonstrated parallel nanoprinting using a nine-by-nine array laser ...

These days, laser is now its own word and generally refers to the device that emits the beam. Let's go back in time and see how this nifty technology came to be and evolved into the handy tool it ...
