Japanese Scientists Manage to Fire The World’s Most Powerful Laser Beam
Japan is way ahead of the rest of the world in robotics, and now it looks like it is also going to take the lead for creating giant laser beams for world domination.
The laser in question can be found in the Osaka University, Japan, and is capable of producing 2-petawatt pulse. It is possible due to an integrated device named Laser for Fast Ignition Experiment, aka LFEX.
Don’t worry, they won’t actually be using this laser for world domination….Hopefully.
Researchers were able to make this laser beam sustain for a trillionth of a second, but it had consecrated energy that is equivalent of 1,000x the world’s electricity consumption.
LFEX is roughly 100 meters long and constructed using a series of glass ‘lamps.’ The structure helps amplify the beam as it travels through.
LFEX concentrate the power of the laser with 200 joules of energy. Junji Kawanaka, an engineer at Osaka University and member of the LFEX team said:
With heated competition in the world to improve the performance of lasers, our goal now is to increase our output to 10 petawatts
However, world domination and space battles aren’t really possible with this laser.
Michael Donovan, Associate Director of Texas Petawatt Laser program, said:
If one wanted to destroy a satellite, the Japanese LFEX laser would not be the answer, as it would not propagate far through the atmosphere – even if it could be pointed towards the satellite. The higher you get, the thinner the atmosphere. So a laser launched in space could propagate, but a petawatt laser is too large to economically launch into space.
Well, even though we can’t use it for taking down space ships, LFEX is still a very cool device.
