These glass lamps were able focus the beam to boost its energy as it passed through. The laser is 100 meters long and although the laser beam it emitted was very powerful, the energy of it could have only run a microwave for two seconds. According to the scientists the laser “instantaneously concentrated energy equivalent to 1000 times the world’s electricity consumption and entered the record books as the most powerful laser beam ever emitted.” Nothing was blown to pieces in this experiment. Researchers explain that the goal is to emit a laser beam that is 5 times more powerful: 10 petawatts.
Back in 2012, in an article in the journal Plasma Physics and Controlled Fusion, researchers first introduced their powerful giant laser. Only now, after three years have passed, did the team of researchers at Osaka University in Japan get to actually firing it at record-breaking power.
