Leaving this for future me to see!

Hello KZfaq

Yeah great stuff

Damn never seen KZfaq comment on a KZfaq video

A youtube comment huh

And completely believable.

"accidentally"

I'd actually be proud of any floridaman if he did that, even if it wasn't this awesome cat. That would be an accomplishment compared to all the headlines we normally see like "Floridaman gets his 2cm peepee stuck in a prophylactic" Or "Floridaman tries to supercharge his brain with a car battery charger" Afterall, there's already 3,000 Floridamen and 4,500 Floridawomen in the lawsuit for trying to charge their iphone in a microwave.

"Is this cut in half yet?" *meanwhile starts cutting the trees on the other side of the wall*

I'm curious with Florida Laser Chainsaw Man series lol

Goals?

Got a 2 letter organization too now.

What does the BLM, DIA, DOE, FCA, FHA, HHS, ICE, RUS, and SEC want to watch him for?

Even two with the secret service now

Goals being on the SCP watchlist

123 👍

​@@bensoncheung2801456👎

I feel it. It's kinda like a gun but even more fucked up to wave around lmao

I tried to dodge it too😂

@@jamvey99.9 percent of the time you would be right. But that brick has me feelings little sus

​@@tobysonline4356That good thing is that we are filled with alot of fluid, like the tree he cut down the fluids will fill the hole the laser created and prevent it from going too deep to fast.

I /think/ the grounding clip wasn't on it, so maybe equivalent to a visibly-safed gun? Feel like it's worse than a gun that's visibly unloaded (ie. safety flagged), but not as bad as a gun that's loaded but has the safety engaged.

I couldn't believe it when I saw a vid from him because I've been subscribed for a month or more lol "This better be worth it" and holy sh..cow was it ever.

We need to think of legit applications for him now, and also (more importantly) less legit awesome ones

And you can blind people!!!

Blind people? Don’t be cornea. I’m sure he’ll set up rods and cones when he works. Iris I had one of those.

Eye see what you did there.

nice

the backyard scientist deepfake when?

YES

@@nicdasl8497 bruh what are you talking about

@@Jacob-ui6fn look at OP's channel

ULTRAKIL PFP WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

they're basically live machineguns that silently shoot trillions (more) of photons at "high velocity" towards a target. you wouldn't just accidentally jostle a firing machine gun roulwd you

I was wearing a special welding helmet made by IPG in this video, and there a sticker on the inside that says "WEAR IR SAFETY GLASSES UNDERNEATH HELMET" for this exact reason. I was worried the $450 helmet I bought didn't actually protect against IR light, so I called them and an engineer told me it does 100% protect you from the laser, but not stupidity haha.

They aren't toys, they are tools.

@@TheBackyardScientist Remember: *THE S IN SCIENCE STANDS FOR SAFETY AND THE F IN SAFETY STANDS FOR FUN.*

@@twistedyogert so, mantoys

😂 that’s a good point.

with the amount of money and effort it takes to acquire the laser, I'm not sure who would be spending the time washing and printing this way

@@au5music ehhh if you do it right you technically found a unlimited money glitch and you can easily make your money back within a couple days just printing $100 bills

Anyone who's read Reacher:Killing floor will know this

I would wager that is why UK paper money (Now plastic) has different physical sized notes for different values.

I love how he put Bad Apple at the end.

plasma apple

This one bit at the end shocked me the most-

@@thelazygamer8194 plasmapple

I was caught off guard by that

In the event of a world War, Kevin is their greatest asset. That's why they are cool with him

The ATF just hasn't figured out how to classify this as a firearm yet. Once they do.. it'll be limited to the point that it's worthless lol

@@jonslg240 secret service goes after anything money related.... I think that's what he was referring to. He does have a dog though I think, so he should worry about the ATF as well.

you know what? the thing that he does with the bill is kind of classified...

Bro's bouta make a semi-portable Death Star 💀

From lethal to overkill to...manslaughter

"I, 'accidentally', blew up a tank with this overclocked high power laser!"

Styro is gonna replicate it but 100x smaller

Its hard not to think about styropyro when batshit crazy lasers are involved.

in case you werent aware, styropyro just dropped a video trying to answer that very question

I've been waiting a while too, couldn't afford one. But now I have more questions. Laser dishwasher, laser toast/steaks and most importantly, can you laser clean a toilet? Is it legal to erase the faces of money and print your own on it? and more importantly, could you still legally pay with it? Basically it is real money?! Damn, I need one of those.

MORE FRIGGEN LAZERS!

There’s a KZfaq channel called styropyro, I think you’d like them,

@@TheDuckMan2523 sure @styropyro does spectacular things with lasers etc. but ladder he has none of these things yet.

So… I’m a furry, all be it a new one, and this… this got me. 3:40

There is almost nothing practical about it

@@alexandermutter929 it's practical for having fun! That is if you have safety glasses.

Dude!! I had forgotten COMPLETELY about that song, and I panicked as I didn't think I'd get the name. Thank you!

@@DanimeCafe np enjoy listening!

@@alexandermutter929 cleaning is what it was designed to do, also welding looks a lot easier

this isn't true the best counterfeit $100's actually used the same paper as the phone book the cheap stock,you can order the paper

it did used to be harder till they started trying to save money(every penny we make costs 1.6 cents kinda deal) get a counterfeit pen and mark a phone book some of them use the same paper you can even see blue and red threads in it under magnification,hairspray gives it that feel but it will stink if you don't run it thru the washer/dryer

Wouldn't be the first time a government organization told him to take down a video

I'm assuming either the FBI is gonna come knocking, and/or that lazer is gonna be banned erm... Discontinued by the manufacturer now since it's on video what can be done...? Lol (If that lazer is even available to the public in the first place?)

@@GetTheFOutOfMyWay it’s on Alibaba right now

It's been done before, but I do want a Backyard Scientist version

And one of his kind

Very unexpected

A welcoming surprise

Me too

Me too

Yes

Same it’s 12:09

lmao backdoor scientist

The spec of dust thing is actually true too lol, that spec will heat up in a microsecond and burn the lense

Scrapman: you dare oppose me mortal

@@Sherwin657 If you think that's funny I would highly recommend that you check out the safety third podcast, that's where I got it from!

I don't care if someone is wearing protective gear , is your life , you are free to do what you want with it.

Watch safety third they talk on this.

Forgot which ep tho

I agree, about half of a styropyro video is about using the right goggles and gear.

@@RandomInside he dies -> no more videos -> sad

Same, lol.

Ye, some people don't realize that risking a chance of setting your eyeballs on fire can be a bigger deal than chance of setting your house on fire (atleast when it's just your house). I don't know how well can this type of laser reflect off regular metals that it is supposed to be used on, but I suspect some shiny or glass object can send a stray ray into yer face and ruin the retina in microseconds.

a lot of people don't pay attention to the fact that looking at the spot on a wall can blind you a billion gazillion times faster than you can blink

Safety is always first

​@neisjo or in the case of this channel third

I'm your 100th liker here & bye.

How many layers of safety goggles would it take to give the same 1/100th of a second protection of a brick?

@@DDDarray that's a good question

The glasses underneath glasses is a joke from the movie "Airplane!"

It's a cliché.

Honestly I think he's there, just needs the funding.. *Dr Evil inpression* "$1billion dollars!"

Yeah, it’s great. I was just not expecting the “Are you a good boy?” out of nowhere like that. Left me floored for a solid minute.

@@brandonmartine291 yeah that video was absolutely gold. worth a watch

@@drcgaming4195 Link? That was the Odd1sOut guest video right?

@@ChrisD__ it was the mall santa one

"A" watchlist? How about *all* the watchlists!

Yeah. We have laser weapons of mass destruction. These wildfires aren't wildfires. The UK Calls their 50KW laser "Dragonfire" -- it's a bit on the nose, yeah? The US has nuclear based space lasers; that's the purpose of Space Force. Sidenote; Thebackyardscientist is a pretty cool cat. I met him and his mom -- he came into my store to buy batteries to power one of his projects.

its only a matter of time before we see units like this at Ace hardware, or even Target haha. Maybe not these high power CW lasers (continuous wave/output), but the pulsed variety (MOPA fiber lasers). Right now these lasers are in a kind of purgatory, where they are too expensive for consumers, but too much of a liability for industry. I reached out to a researcher who wrote an article about the new trend in handheld laser processing and this is what they said. Hi Kevin, With regards to your interest in handheld laser welding, I recommend you read this article (www.lasersystemseurope.com/analysis-opinion/questioning-safety-handheld-laser-welding) in Electro Optics' sister magazine: Laser Systems Europe. I would very much air on the side of caution regarding this application. We've had readers contact us in the past saying they've bought handheld laser welding systems, however are not able to use them due to safety risks/laser firms not being able to produce goggles for these systems/lack of training available. Also, at a recent laser processing exhibition, a safety firm I spoke with (producer of goggles and windows for enclosures) remarked that they are not going anywhere near this application due to the risks involved, which I thought was quite noteworthy. From what I've learnt myself about laser materials processing technology, the best solution is to always have the laser contained in a Class-1 format away from humans (in a machine, behind barriers with fume extraction technology). It's not like other handheld welding technologies and poses very different risks. That's just my two-cents. But as I say other readers have bought these systems and then just have them lying around gathering dust as they can't actually use them within the safety laws of their country.

​@@TheBackyardScientist So what you're saying is... only a brave enough man can use it? Man it truly is a shame that such a thing is reduced to a toy for adult kids to play with, i've read a bit of that article to check cause i've thought it's not worth it cause of the upkeep but it truly is just cause of safety and lack of awareness in this field? That's just sad, but as you've shown safety is nowhere near this thing, you could kill a person in a second and make them blind in a fraction of that. But how do you make a death laser safe? Yeah general use isn't ready for this, but at least some people can use it as private owners and for a content creator like you this is golden. Since this field is still active i'm looking forward to many uses for lasers anyway, maybe in space, where there isn't a lot of things to burn and breathe in, but i don't wanna jinx the laser making a disco party on some planet bajilion lightyears away

@@pikusek2550 class 1? try class none!

@@TheBackyardScientist i already thought your 200w laser was absolutely illegal but this right here is a whole different dimension. still hard to believe that its allowed to have this.

To be fair, people probably said the same thing about other technology that was hazardous. As long as it has safety features that stop it from being dangerous, it's ok.

same

and give it to the next person

Now converge 50 of these in one and try to cut down entiere houses. Be sponsored by mr beast

the invisible spectrum has more energy than a wimpy green laser. It would probably just burn a hole in the crystal.

That’s oddly specific

@@darkshadowsx5949 Literally none of what you said was right, and most of it didn't make sense. For a start, the spectrum has no influence on the amount of total power (beyond the energy per photon - which green actually has more energy then IR). The wavelength of light affects the absorption of the target material. If you want to cut copper, Green will do far better then IR, as 532nm is absorbed much better then 1064nm. On the other hand, if you try and cut something that is green with a green laser, it won't go as well, as most if not all the green light is reflected off. Nonlinear Crystals actually requite extremely high peak powers to even work. The crystals become more efficient, and the effect becomes more prounounced as the intensity of the beam increases. This is why NLCs such as BBO or KTP are usually used with a Q-Switched laser. The laser is focused in on the crystal such that the intensity of the beam is at, or close to (depending on the power density theshold and max electric field densities) it's focus point.

I knew it was empty :P

The wattage would be there.. Not sure about Ryobi but Bosch's ProCore 18V can deliver 1800W in bursts.

Me too but with milluwakee instead of Ryobi because I wanna use it with the batteries I have and not have to buy different ones 😂

Nah, since that would be power hungry garden tool, it will use their 36V max power.

Well at least I thought it was funny.

same

same here but it was cool, I like his style hahaha

We need a laser off. Who can build the most powerful laser.

He had one until he blew the crap out of it when he tried to increase output power

@@TheBackyardChemist styropyro had one of THESE? And beefed it up?!

@@MattH-wg7ou Nah but he had a pulsed laser that made really short laser pulses with an insane peak power that could ionize air.

what is the strongest laser he has? i thought its only 45 watt. even the backyardscientist had a 200 watt laser in one of the previous videos. styropyro has to catch up (maybe by building one of those military grade lasers with 2 mega watt of power).

Always good to see the classics

Glad to see you here, man!
