Boffins in Shanghai, China, have been designing the world's most powerful laser.
The team has already made history with its earlier invention, the Shanghai Superintense Ultrafast Laser Facility have already set records.
The machine is small enough to fit on a tabletop, and contains a disc, the width of a frisbee, which is made of titanium-topped sapphires.
But this small device, by pushing light through the crystal and refracting it off a series of mirrors and lenses, is able to produce unbelievable amounts of power.
The laser set records in 2016 when it produced a pulse of 5.3 petawatts (million billion watts).
The blasts are incredibly brief, lasting less than a trillionth of a second.
