The most powerful laser in the US recently produced 2 quadrillion watts of power

  The laser produced power? How do we harness that so we can power the world with lasers? 🤔

    It’s no different than an engine producing power. I think you are confusing it with “energy”.

  The key thing here is the burst lasted for “25 quintillionths of a second long”.

  Meaning it had a total output engery of 0.05 W/h, or how much energy a standard US space heater outputs over the course of an eighth of a second.

    could this boil one molecule of water?

    You multiply seconds with seconds per hour and somehow get “per hour” as the final result? But even ignoring that error, what is W/h supposed to be? Rate of change of power?

      Also, it is a small k for kilo and you don’t write it as 4.310^18^[unit]. Just 4.310^18 [unit]. Or 4.3E18 [unit].

    So 25 attoseconds… That is impressive. The power record holder right now is the Măgurele laser in Romania, at 10 PW, but it lasts a thousand times longer, at 25 femtoseconds I believe.

  I have a decent grasp of physics but I understand nothing at all about this article. Melp me out, please?

  What use is a high energy beam that last for an almost immeasurably short period of time? How can it even be said that it has this power output, in such a short time?

  “Zero-POW!-zero” sounds unbelievable to normal humans. No ramp-up? No sizzling out?

  On such a short time scale, what’s the actual Wh used? It can’t be very much, so the actual energy delivered can hardly do anything at all, either.

  And finally, what’s even the point of this? What’s the purpose? What’s the end goal? Why?
