As per reports, Japanese scientists from Osaka University have recently fired up the most powerful laser in the world ever. The Laser for Fast Ignition Experiment (LFEX) fired up a 2-petawatt laser beam, claimed Japanese scientists.

Researchers said there is nothing to worry about the laser because so far our current technology does not have the ability to sustain this kind of power long enough to do harm, not even a second. The laser of LFEX lasted for one trillionth of a second.

According to Engadget, the 2-petawatt laser of LFEX reached a length of 300 meters. Researchers said as the laser was sustained for barely the blink of an eye, it only used a very low amount of energy.

LFEX will only require huge amounts of energy if it gets amplified over a span of 300 meters through a series of glass lamps, said researchers.

The concentrated amount of energy contained in the recently fired LFEX is tantamount to 1,000 times the total electricity consumption of the whole planet.

It has been said that the laser beam used in the experiment is housed in Osaka University's Institute of Laser Engineering and measures 100 meters long and includes a contraption used for observation purposes.

Researchers associated with the work performed the experiment using fluorescent tube lamps that served as the conveyor for the energy. Further in explanation they said the energy applied to the glass lamps was amplified repeatedly until it reached the optimum capacity that can produce a 2-petawatt laser.

Junji Kawanaka, an electrical engineering professor at Osaka University who is part of the experiment, said that because of the tough competition in the world they will work hard until they are able to produce a 10-petawatt laser.
