What kind of cancer does that cause?
Very cool though.

Laser rust removal guns anti cheap, they can start at a few thousand dollars.

Whatever they cost it's got to be worth it if you do a lot of restoration work like that. I've never seen anything like that before. Very cool.

More like several to a few hundred thousand dollars. Otherwise I would all ready have one.

That's it? It looks like it has two feeds/cables in the back of the "gun".

Why can't this be as popular as cell phones so we can go from the box in the car(this), to a handheld portable version for a little of nothing in ten years. I would thereafter be known as bimmer, lord of rust.

Google says the cost from $80,000 to $480,000.
Woohoo! Made in the U.S. of A.!

Now I know why I don't have one. It appears to not heat the item it's cleaning. I could see this replacing sand blasting.

Priced one of these out at a previous employer where we were responsible for rebuilding/re-certifying oilfield wellhead equipment. The man hours we spent stripping every petroleum based chemical under the sun off that equipment, rebuilding it, painting it, shipping it out, only to have to do it again the next fiscal quarter were staggering. The system we looked at wasn't anywhere close to the numbers you quoted and would have paid for itself in a few months if my direct supervisor would have presented it better to management. As it was, they damn near soiled themselves and I didn't get a laser to play with

Care to share brand and price Info, if I could find one within reasonable reach I'll buy one and Start a business.Priced one of these out at a previous employer where we were responsible for rebuilding/re-certifying oilfield wellhead equipment.

Don't worry, in five years you'll be able to use a 20% off coupon to buy one while inhaling that putrid rubbery smell. It'll make your balls glow at night, but hey, it'll be "good for the price!"

I'll see if I can dig up the brand. The pricing we were looking at was somewhere around $40,000-50,000.
The justification was we were billing $50/hr per person in the shop, had 4 guys on the cleanup crew so $200/hr total. Comes in at $2,000 a day (including consumables), so $10,000 a week. You knock the 40% off of that for federal and state labor taxes, benefits, etc, we had roughly $6,000/wk to cover their wages and any equipment we needed.
Of that $6,000/wk we were figuring that $3,000 could be justified towards the equipment while dropping the crew size to two operators.
That would have given us roughly three months to pay the equipment off, with a grand total ROI target of 6 months.
Now, none of these numbers are solid, take them for what they are worth as I haven't worked for that company for a few years now and don't have copies of those documents any longer.
That's cool but I'd like to see the other component the cable goes to.
Is it 3 phase?
What is the duty cycle? Lasers produce heat, it could be that the vacuum system also serves to cool the lasers.
I think there are 5 classes of lasers from laser pointers to ray guns. For sure levels 4 and 5 produce radiation and require a certification to run. ($1000). Anyone looking into the beam or a mirror reflection of it could get exposed to cancerous radiation through the eyes. Severity depends on what classification level it is.
Bet the glasses cost $300
Nice but I think there are still some hurtles to jump before it replaces our sandblasters.

Buy a $4K tool to remove rust off a $20 tool. Think I'll stick with Evaporust for now.

so, about N years ago (15? 20?) NASA funded some guy in (i believe) chicago who was working on a way to take a ceramic plate, and with suitable magic, move heat from one side to the other.
why? well, as it turns out, NASA funds all kinds of interesting things (i worked on a NASA software contract when i was a "young turk"), but they wanted this for cooling electronics in harsh environments. ya see, most cooling systems need to move something around (gas or fluid) to work. this one didnt, it was solid state. it could be 300 degrees outside, and it would still move the heat from the 125 degree side over.
after funding the work, they bought a bunch, various sizes, for several thousand dollars a square inch, as covered in the contract. NASA was happy, they had solved an "unsolvable" problem for a few hundred thousand dollars, and didnt care about the technology after that. he owned it all outright.
but . . .
so, there he sits. his only customer has bought all he would ever need. there weren't that many other people interested in them,at least for those prices.
so, he did some more work, and figured out that he could build one to lower standards that would only work from about 35 to 125 degrees, and was reversible. if you flipped positive for negative, the heat moved in the other direction. and, he could do it for about 5$ a panel for something that could deal with a container of a small number of cubic feet.
have you bought one of those plug in car coolers like this:
https://www.amazon.com/dp/B007ZYH4BM/?tag=atomicindus08-20
yep, same thing. they add a small fan to keep the transfer pad from getting too hot. some of these units also keep warm food warm, with the flick of a switch. (daddy, how does the thermos bottle know whether to keep the stuff inside hot or cold?)
it might take a few years, but those lasers will be available for a reasonable price. not tomorrow, but not infinitely far in the future, either. i expect they will drop down in levels, to open up new markets without undercutting themselves before they have sucked most of the profit out of each level.

that certainly looks right, although the wikipedia entry doesn't mention the guy in chicago.

Interesting I wonder just exactly how it works. It looks like the laser burns the rust off yet I don't see any pitting left after the rust was removed.
I had some work installing some level 4 laser equipment this spring. My role was strictly involving the installation and had nothing to do with the inner workings of the equipment but I did gleam some info from the techs on hand. The units were cutting edge, only 5 in the world at that time and used Peltier elements for cooling however hoses the size of the vacuum line in the video above carried coolant to a bank of chillers required to cool the Peltier elements. While the Peltier elements could sure enough pass the heat produced by the lasers that heat had to be quickly and constantly moved along. The chiller units themselves were required to be kept in a cold room to ensure they could sustain their role in keeping the coolant at temperature. Condensation is another issue. I have no doubt that over time this technology will improve but I wouldn't hold my breath. I'm no expert in laser technology but the amount of heat lasers of this lever produce seems to be a major obstacle for keeping these tools small and practical.
I'd like to see the rest of the apparatus attached to that gun in the video. Here are some images I got from googling "laser blasting rust":
