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...

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.

$6.5k AUD 3 years ago for lasik. Prk would have been 5k. I wouldn't be worried about mistakes, the opthamologist does the procedure like 15 times a week and the laser machine is tracking your eye movement at 1kHz. Mistakes are almost unheard of. Where your issue may lie is if your eye is physically not good for the surgery, like if your prescription is too strong or cornea too thin. They do a bunch of tests and discuss what's right for you.

I think...$5,500 in 2005? Probably not relevant to today's prices. I would imagine the equipment has made things a bit safer and easier, which would probably ... Well I'm sure it wouldn't drop the price because who ever does that? But it probably kept it from rising too much.
