The HERCULES Petawatt Laser at the University of Michigan, USA, can produce a focused laser beam with an intensityof 2×1022 W/cm2 (20 billion trillion watts per square centimeter). The laser is fired in a pulse lasting just 30 million billionths of a second and its intensity is equivalent to focusing all the sunlight that hits the Earth onto a single grain of sand.
