Experts found the best of all lasers


Scientists have developed the mother of all laser beams — one that has focussed power equal to all the sunlight heading Earth’s way.

Sciencedaily reported that, this newly created record-setting beam ,created by the Researchers at the University of Michigan ,measures 20 billion trillion watts per square centimetre.

The laser contains 300 terawatts of power, or 300 times the capacity of the entire US electricity grid, and its power is concentrated in a 1.3-micron speck — about one-100th the diameter of a human hair.

A beam like this cannot stand for long.This one lasted just 30 femtoseconds. A femtosecond is a millionth of a billionth of a second, the researchers said in the online edition of the journal Optics Express.

The team managed to get such high power by putting a moderate amount of energy into a very, very short time period.

In addition to medical uses, intense laser beams like these could help researchers explore new frontiers in science.
