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. MORE
