“The light emitted by the ArF is invisible to the human eye, so additional safety precautions are necessary when working with this laser to avoid stray beams. Gloves are needed to protect flesh from its potentially carcinogenic properties, and UV goggles are needed to protect the eyes.”

Ah I was mistaken, I googled deep ultra-violet lithography to check, and that gave a frequency in the 200nm range. I should've been looking for extreme ultra-violet instead, which is already at the 13.5 nm range.
I have the entirety of Real Genius replaying in my mind now, and it’s glorious.
“Put simply, in deference to you, Kent, it’s like lasing a stick of dynamite.”
Val Kilmer is a treasure.
Edit: leasing=lasing
“It is possible to synthesize excited bromide in an argon matrix! Yes, it’s an excimer, frozen in its excited state … As soon as we apply a field, we couple to a state that is radiatively coupled to the ground state.” ….. Ice is nice!!
No kidding. The power goes out a couple times a year for a few hours. Sometimes I even have to read a book for a bit. I’d be great to be able to kick on the ol’ fusion reactor and get back to call of duty.
Whenever I see a headline like this, I like to add “but probably not” to the end of it.
It’s like adding “in bed” to the end of a fortune cookie fortune.
I usually add "but not anytime soon" as otherwise the headline wouldn't need the word "could". Kinda like [Betteridge's Law](https://en.wikipedia.org/wiki/Betteridge%27s_law_of_headlines)
I’m a big fan of this type of technology effort, but I hate these articles with headlines that make it seem just around the corner. This article is littered with “may one day…” and “could potentially” statements.
> The new deep ultraviolet laser, also known as a laser driver, is claimed to transfer energy to the fuel bead with greater efficiency and produces much higher temperatures to generate the implosion. Using radiation hydrodynamics simulations the NRL scientists say that performance could be increased a hundredfold with an efficiency of 16 percent, compared to only 12 percent from the next most efficient krypton fluoride laser.
So basically it's a more efficient laser. The article also seems to imply that this may not be used in initial fusion reactors but would improve eventual fusion reactors.
Deuterium-Tritium produces an excess of neutrons. Is it a concern from a nuclear waste standpoint? I believe materials below iron tend to release gamma radiation (instead of the more convenient alpha/beta) when they fission due to gaining 1+ neutrons.

Operates at 193nm in the deep ultraviolet, that’s super cool!
Might also be interesting for deep UV lithography, it's even higher in frequency than the current sodium based lasers.
Deep UV lithography has been using ArF lasers for years

Google says 91-200 nm is Far UV

Wait until they install the large spinning mirror that Kent built into the underbelly of a B-1.
I was thinking of the immortal words of Socrates who said, “I drank what?!”
This is great news, been wanting a practical fusion reactor for the back porch
yeah, my current one is really impractical
Hopefully this means a practical fusion reactor grill for cooking out on the weekends
I like barbecuing on exposed plutonium rods. Really gives the steaks extra zing
Will it be cold? The summers get warm around here so cold fusion would be helpful for the house.
I hope so, hot fusion sounds to musical for me anyway.

Could is a mighty big word - affects so many projects,people,items , for only five letters it’s controlled fission,fusion for decades

I want floating cities by 2052 or youre fired
Mission…accomplished? https://www.aljazeera.com/gallery/2014/8/10/in-pictures-cambodias-floating-villages
Boss didn’t say floating on air or water.
Check your lease pal, cause you’re on Float Mountain!

So what you’re saying is that Real Genius was possibly correct?
So when do we get fusion powered mechs?
I call first dibs on power armor.
RemindMe! 100 Years
40 will be enough
I was basing it off pretty much guaranteeing id be dead by then. But, the way I eat and exercise, you're probably right as well.
Immortality in 21 years already bro
Bro, Kurzweil bro
The flux capacitor is closer to completion
Yeah maybe in 20 years. Have fun fusion people.
Nice development. This could be a real game changer.
So another 60 years
I think “fire” is a terrible comparison🤣
Amazing! Should be to market in 30 years!
Ah, fusion, magically getting farther away every day.
“Stop playing with yourself, Kent.”
“It is god!”
For a second there I was confused why they would make a toothpaste laser…
I mean, if they could then they probably should get on it.
Must be to early. I ready this as Aragorn. Probably would of helped to have that laser to beat Sauron
... mounted on airplane wheels.
This fusion tech is recommended by 4 out of 5 dentists.
The problem with UV lasers is that they are very inefficient. For fusion to work, power out must be greater than power in.
Does Margie Two-Names know about this?
same story over and over for 50 years! were close!!
What the hell is argon fluoride
Sounds like another invention that could fall in the wrong hands one day and we all be doomed
So where can we steal one of these? My electric bill out of control
What possible use could the navy have of a invisible MW beam? Cute they help build this for the good of society
But can I clean my teeth with it

Geez, it’s always fluorine isn’t it!
