Billion-times more efficient nuclear fusion could be unlocked with low-frequency lasers (interestingengineering.com)

...“The calculation results show enhancements of fusion yields by orders of magnitude with currently available intense low-frequency laser fields,” highlighted the study.

For a collision energy of 1 keV—a level where fusion is normally almost impossible—the application of a 1.55 eV low-frequency laser can transform the reaction rate.

At 10^20 W/cm² intensity, the fusion probability increases by three orders of magnitude, while increasing the intensity to 5×10^21 W/cm² boosts the efficiency by a staggering nine orders of magnitude.

This dramatic increase effectively makes fusion at 1 keV (relatively low temperature) as probable as fusion at 10 keV without laser assistance...

Lasers make everything better

Except blindness.

Idk man lasers definitely made my vision better. Better than 20 20 now

How much did that cost? I would just be afraid of them making it worse with a mistake, but I knew a girl that said it was the best decision she ever made.

Oh there are lasers big enough to cure everything. Well, the person doesn't worry about the disease and you can't get it. Yes the person does disintegrate in the process but they are working on it. No wait, they're done working on it. Anyway, anyone else needs curing? No? Its a laser miracle!

Anyway seriously, lasers are dangerous if the person using them does not known what they're doing. If that's you, stop.

Mark rober has a laser versus lightning video, they test burning through stuff with a powerful laser and tesla coil or whatever.

It is cool, too bad eye protection costs so much, as much as the laser itself I hear.

If it's merely legal blindness and not total blindness, they can still make it better.

That's just how cool they are. Gotta specify the type of blindness, even.

They can even cheer up ill-tempered sea bass.

Everyone needs a frickin bone tossed their way here and there.
