The most powerful lasers in the world are used for fusion research, and are around one PetaWatt. This is a thousand million million Watts. A 1 Watt visible laser would be enough to blind you, and 100 Watts can be enough to cut through flesh. These PetaWatt lasers are seriously powerful.
Wow that laser is seriously impressive (acctually it’s 192 lasers focussed on one spot but it’s still pretty amazing) If you are interesting in learning more here is a link to their website:
I actually don’t know, but I’m interested so I’ve done a bit of a web search.
This article in the Telegraph seemed pretty cool
“Capable of producing a beam of light so intense that it would be equivalent to the power received by the Earth from the sun focused onto a speck smaller than a tip of a pin”
