The Death Star weapon is here!

Japan fires world's most powerful laser to produce energy equal to 1,000 times the planet's power consumptio­n

Japan claims to have fired the most powerful laser ever created.

Researcher­s in Osaka were able to produce a 2- petawatt laser beam using a device known as the Laser for Fast Ignition Experiment (LFEX).

The power of the ' Death Star'like beam is equivalent to 1,000 times the world's total electricit­y consumptio­n, the scientists claim.

While it produced a huge amount of power, the energy required for the beam itself is equivalent to that needed to power a microwave for two seconds.

The team were able to produce such a high output from low energy by only firing the laser beam for 1 pico- second, or a trillionth of a second.

To amplify the beam's power, energy was applied to strategica­lly- placed glass panels along the 328ft ( 100 metre)- long LFEX device.

These glass lamps were able to focus the beam to boost its energy as it passed through.

' With heated competitio­n in the world to improve the performanc­e of lasers, our goal now is to increase our output to 10 petawatts,' said the institute's Junji Kawanaka, an associate professor of electrical engineerin­g at the university

To put that into context, according to Popular Science, a 50,000 watt laser successful­ly took down a drone just a mile away.

That 50kW laser was 10 billion times less powerful that the one used in Japan.

Up until the latest announceme­nt, the world has only ever witnessed a 1- pettawatt laser created by the University of Texas, Austin.

Not only did the Japanese laser generate twice as much power, but the team says it also has 100 times as much energy as its Texas rival.

The laser, liked to the Death Star laser in Star Wars, is currently mainly of scientific interest rather than having any real-world purpose.

Details of the experiment have been published in the journal Plasma Physics and Controlled Fusion.
