How Do Laser Beams Engrave Things? (slow motion) | WIRED

A fiber laser can carve super intricate designs into any metal in just 10 seconds. The laser is getting so hot the metal is vaporizing away, yet it does nothing to our skin. As we play the video back and watch these lasers in slow motion, Alexander Sellite of "Laser Everything" breaks down everything we need to know about fiber lasers and how they function.

Thank you guys so much for coming by the studio. It was an honor to be able to work with you and show off this amazing technology!

If 180fps ‘slow motion’ is the best your hardware can do, why not rent a phantom?

1:42 - B roll plasma cutter, not laser.

[khalilahd.]

This is actually incredible. Crazy what technology can do these days 😅

How can you call 180fps slow motions... Oh my god, bring the slow mo guys to film this.

I’m a member of the Laser Everything community and you won’t find a better place to learn and share your knowledge with other laser businesses owners. Great YouTube channel and social media accounts.

It is called a fiber laser because the laser light is both generated and delivered by a fiber optic cable.

Laser everything is the best place to learn about this kinda laser

[sweebos]

This was amazing to see! I knew a tiny bit about this process, but this was informative and incredibly entertaining.

@0:31 so with 60W power 1070nm wavelength doesnt interact with organic material? i have heard bad stories in laser safety classes, could you please explain a bit more? Thanks.

No Alex? Didnt expect to see you on Wired!

There's actually *many* aluminum alloys, aluminum may be an element, but you'd be incredibly hard pressed to find yourself using raw aluminum.

I would love to hear more about how iron can turn blueish or red/brown/blackish depends on the oxygen level react to the laser. ;)

I had no idea you could do color that's wild

[masterix]

Can't you also color titanium with the same techinque as steel?
Has far as I have seen, the titanium oxide layer changes color depending on heat as well.

[yoyofargo]

my jeans have laser engraved fold marks lmao

[nesthi]

I'll say it. The yellow sparks are cool looking!🙌

[fralinsandfriends]

That's awesome. It looks like a lot of fun. 😁😁👋👋💖💖

[ellislaserengraving]

That is so awesome. I can't wait to learn so much more to get my business going. I have found the right place to learn everything about galvo lasers.

The mirrors move as fast as 10, 000 milli meters per second! No wait, the mirrors move as fast as 10, 000, 000, 000 nano meters per second! (Also known as 10m per second, but doesn’t sound as good)

[AfrozAlam-gdvp]

3:13 is the metal moving because of laser hitting or because lase is making the metal hot?
