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.

      Interesting video and your channel name is awesome on the T-Shirt! So how much does a fiber laser cost?

    • Nakedlunch02

      October 16, 2022 at 6:18 pm

      @Laser Everything were the color markings done on a standard fiber laser or a mopa? I wasn’t aware you could change pulse width on standard fiber laser if so .

    • Laser Everything

      October 26, 2022 at 12:11 am

      @nessi doe They’re getting pretty cheap these days, used to be much much more but you can get started for around $2500 with something decent.

    • Laser Everything

      October 26, 2022 at 12:12 am

      @Nakedlunch02 They were done on an SFX 60w M7-M-R C-series MOPA fiber laser

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

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

    Technology has come very far

  9. Krish

    October 5, 2022 at 8:30 pm

    @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.

    • Laser Everything

      October 5, 2022 at 9:39 pm

      There are obviously tons of exceptions like color, density, temperature, but in general – organic materials have a very poor absorption rate at this wavelength. That said this short IR is very dangerous to your eyesight so you should always wear safety glasses when working around these machines. Especially non-enclosed class 4 lasers. We get into it more on the channel but the long and short of it is it isn’t going to burn the crap out of you like a UV or CO2 laser would if you catch your hand between the beam and the object.

  10. 3k2p6

    October 5, 2022 at 8:37 pm

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

  11. Justa Youtuber

    October 5, 2022 at 9:11 pm

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

  12. Janet F

    October 5, 2022 at 9:43 pm

    It’s probably a good thing that I’m not rich; I would totally impulse buy one of these and not have a clue how to use it, even after Alex has explained it to me. Better I should just watch, so thanks for this! 👍✌

    You can buy low power ones that run on 3d printers. They are rather dangerous as they can blind you without proper eye protection. The smoke is aweful.

    Video is fine, but if you mention slow motion, I’d suggest getting appreciable slow motion footage if possible. I’m pretty sure everyone would have thoroughly enjoyed something better than 120-180 fps. Anyways, have a nice day!

  48. thoobonator

    October 9, 2022 at 7:27 pm

    Good informative video. It would have been nice with an explanation to why the colour actually appears. I assume it is because steel has a colour change pattern that it will go through when it reaches different temperatures.

    Guess I shouldn’t believe everything on the internet 🤣

    • zapro_dk

      October 16, 2022 at 4:51 pm

      That was a CO2 laser cutter. It has a wavelength 10 times as long, and it’s optimal for organic stuff.

    Always weird seeing the word ablation, as someone with cardiac issues whos has cardiac ablation, meaning I had a procedure where went through my femoral artery in my leg (inside the artery) all the way up to the inside of my heart chambers and ablated lots of parts of my heart (burning/scarring parts of my heart muscle to try alter or permanent damage certain electrical pathways across the heart).

    My cardiac problem means my resting heart rate 24/7 is tachycardic. Averaging 150bpm up to 250bpm. Day and night, awake or asleep. Nothing works to slow it, no medication, no Adenosine. Not even shocking my heart over and over fixes it (and this hurts, they do it whilst you’re awake with a little bit of sedation!).

  57. rock_paper_celery

    October 11, 2022 at 3:33 am

    This is cool but I’m disappointed they didn’t explain how the color is created. “Steel is ferrous,” but iron is not an inherently colorful material. I’m sure it’s some kind of thin film interference effect, but the fact that they didn’t mention that and just said “it’s ferrous!” as if that would be enlightening is kinda lame. Better to just be like “how the color works is out of scope for this video.”

  58. Masterix

    October 11, 2022 at 1:02 pm

    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.

    • Laser Everything

      October 15, 2022 at 3:55 am

      Yes that’s true, we haven’t experimented with it too much so I figured I’d keep it simple here as it acts more as an intro to lasers but you’re absolutely right.
