Homemade YAG Laser from SSY-1

[delukin]

Nice watch

[nave4pres2]

but will it blend? JK good work!!

[magna59]

Very impressive ........ bit of a blunt instrument . But very impressive.

[thatoneguy99100]

circuit shematics? I have the same head

[PyroForge]

Nice setup! Try putting a lens on it...  With a nice strong lens (about 1" focal length) I've been able to punch holes in aluminum foil with mine.

[Immaculite]

wow some body gots lots of fuckint ime on their hands!

[CriminalMacabre]

It's a nice example of how burst is more effective than continuous beam, experiments like this could set the basis for future laser weapons

[MagicSysRqKey]

Could also be a bomb...

[Djich1]

Hello

you sell the laser??

if so write me back

I'm fascinated by the laser

mfg david



[sajid9460]

very nice work keep it up

[psiewert83]

Please tell me you didnt use speaker wire to run those lines?? haha

[HomebrewGuru]

For some reason my SSY-1 isnt burning as much... Perhaps my beam diverges too much? What is optimal for the greatest burning power?

[SuperKingcobra33]

Finger finger finger!!!

[vallertsi]

Can you make video how you make this.

[Theorigionaldjsdot]

Cooool. I want to think of something clever to say,,,,but cant so i will add this to my faves. Ive not seen a laser that can burn that quick

[Rayz093]

A real life laser gun?

[rendygaul]

+1 again...

[Si3z3]

LOL its a hole puncher for ink XD

[activflap]

I looove pancakes :D

[rshfn44]

cool! I do maintenance,alignment & collimations on yag lasers at my work place. 350W pulsed,ND Yag

[IonLaserMinistry]

Nice set up there!! Ive got the same head,and I was wondering if you could show me how you wired it all up?



[FrigginSmift]

@IonLaserMinistry Its a pretty simple setup using flash caps and the small inverters and triggers you get out of disposable cameras. The inverters are pretty weak and i have since dismantled this laser and stored it away till i can get a better inverter. the descrition under the video has got a good overview of how i did the caps, im not sure it would all fit in this little message.

[kaligula785]

well i guess in 5 to 10 years will have the first lazer (phazer) guns homeaide of course huh live long and prosper i guess haha

[rendygaul]

is this just like a ruby laser ? (the mechanism)

[DryQuLa]

@rendygaul It's pretty similar... They both use a single-crystal rod, and can both be flashlamp pumped, but diode pumping the YAG with 808 nm is more efficient. Oh, and the ruby is a 3-level laser, which means the pump power has to be very high compared to the YAG, so the ruby flashlamp is usually helical, with the rod in the center. Almost all flashlamp pumped YAGs I've seen have a straight flashlamp next to the rod in a polished elliptical cavity.

[TheSuperhack3r]

looks like a bomb when you opened it up the first time :)

[TheNuclearWatermelon]

at what voltage do you fire the capacitors

[TheNuclearWatermelon]

what was the total cost to build this?

[phikre]

really nice and easy setup!

Where did you get the laser head and how much was it?

best regards

[FrigginSmift]

@phikre Thanks! I got it off of ebay some time ago for $125. I think the last time i looked the price had gone up slighty, its still a good deal in my mind :)

[sciencoking]

I know what i want for christmas >.>

[mewrox99]

I hate to think what a direct hit in the eye would do! Ouch

[mewrox99]

What wavelength

[TheNuclearWatermelon]

@mewrox99

1064nm

[kaboooom2000uk]

Hi, nice little setup u have there, and it does a fair ammount of damage for somthing unfocused (looks unfocused...?). How many joules do you estimate is in the pulse? If you know the uF of the capacitor bank and its voltage that will be enough for me to go on. Im assuming you are using all the 8 capacitors, and waiting for them to get to a certain voltage before firing correct? If so whats the voltage at the point of firing? nice work.

[FrigginSmift]

@kaboooom2000uk Its unfocused, the light emitted is fairly coherent as is. I don't know how many joules the pulse is but i do know how much electrical energy is dumped into the lamp. In the vid it was getting about 45~50J from the caps, i have since swapped out the caps and made a new bank that gives it 60~70J. Thats just electrical energy in the bank, as to how well the flash lamp and rod convert that into laser light is beyond me :)

[kaboooom2000uk]

@FrigginSmift Thanks for the reply. me either, the complexity of designing an efficent laser head i leave to the pro's, but thanks for the figures, I wondered as I may buy one of these laser rods off ebay or somwhere, and have a go at my own. Question, did you have to buy any mirrors or anything, or did the laser head come as a complete assembly out of another device?. Thanks for this video.

[FrigginSmift]

@kaboooom2000uk Not a problem :) I bought the head off of ebay as a complete unit. The head is from surplus laser range finders that have been replaced with diode lasers. The laser head will come as a complete unit, rod, cavity, flash lamp, mirrors, q-switch, and housing all put together and aligned. The way its made is very sturdy and doesn't need to be aligned or tweaked, just give it power and its good.

[sigloz11]

MOAR BATTERIES!!!!!

[nhojmabon]

nice

[bloodyman125]

yag gay get it

[alejandroengineer]

I would like to know if you laser emits a smell, I have a yag laser too but it emits a smell, but it isn't ozone.

[FrigginSmift]

@alejandroengineer Nope, the only smell i get is from the burned target

[orangedac]

be careful of your eyes.

even the back scatter can damage it.

please consider getting protective goggles for a wide bunch of wavelengths

[Jpyromarine]

So I'm guessing if anyone builds a laser gun a yag laser would be used

[snowman3514]

is it drilling holes in that tape?

fuck man thats powerful!

can you run yag lasers continuesly or just pulsed like yours?

and where did you get the schematic for the driver setup??

thanks

[dirkbruere]

Have you tried putting your hand in the way? :-)

I probably would.

Anyway, be very careful of reflections and eyeballs.

[hboy007]

Nice! Now everything in your house has beautiful burn marks :-)

[TheQlabs]

Hahaha i love this old skool video, reminds me of the mi6forums,...

[QuarterSticks]

how many watts is this laser?

[FrigginSmift]

Hmm.. i don't know. Its a flash pumped laser so i really don't have anyway to test its output :/

[Mato0092]

@QuarterSticks That could be easily like 1 megawatt, because the pulse is really short and it can do so much damage is such a short time...I think :)

[diegoribadacunha]

got the same problem... can´t find a german seller of Yag laser rods

[Butandiolmonoacrylat]

Help me!

Where can i get as a german an ssy-1 unit? heres nothin on ebay and the us sellers doesnt expoort :-(

its so bad :-(

[HVdischarge]

I WANT ONE AND I WANT IT NOW!!! Why do they only send to people within the US...grrr.....

[lwctco420]

i knew that they had these!

[44supernoob44]

that is wiked how the hell do you make it

[TylerWdt101]

its awesome!

[transistorbrater]

really nice laser !

could you please tell me where to get one of these ?

i am searching for more than two months for a dealer who ships these to germany, but i only found a guy who sells it for more than 400$.

[FrigginSmift]

I got mine off of Ebay, the only problem is he only ships inside the U.S.

[transistorbrater]

btw, get a ktp crystal, and pump it with your ssy-1 , this will produce a very very very (did i mention the word very ? :D ) bright green laser flash.

[Mato0092]

@transistorbrater Ok, but will that flash not blind me? I actually have SSY-1 and a KTP, but I am waiting for a trigger coil to arrive...so, is it safe to use a KTP with this if I only have Anti-IR goggles?

[DryQuLa]

@transistorbrater Yeah, man. 535 nm is REALLY bright, but just make sure to watch your power density, or you'll have a very very very broken crystal :(

[M4ST3RL1NKX88]

@FrigginSmift

U.S? Awesome! So now I can have one of these!

[creativeboy1]

how much did you pay for that? and where did you get this idéa?

[FrigginSmift]

It was 125$ shipped.

I had known of this type of laser technology, but most setups were pretty pricey and complicated. When i found out about this unit i jumped at the chance and got it going.

[car6on14]

hey, nice work on your projects, all look like they have been built very well.

[arielniznik]

yay! you posted it! this one is amaizing!!! wow. you were right about having to be careful about where you aim it. haha

[feefoofii]

use this to destroy all those who called you a nerd in high school.

[spoofinkids2]

dude awesome

[layer18]

I think you should work for ASAN!!

[FrigginSmift]

Yeah, its got good range, the only problem is knowing where the laser is going to go as it fires in pulses and the laser beam is completely invisible :P

[HVdischarge]

Hey its me again lol.

nice!

what size yag rod does this have?

MAKE IT CONTINOUS (you know you want to) :-D.

i like the case!

[FrigginSmift]

LOL, i'm pretty sure the doping level of the rod is way too high for continous operation, would probably be destroyed in a matter of minutes.

The rod is 5X60mm

[HVdischarge]

Oh :-(....  maybe buy a few more and have them fire in sequence? (if you win the lottery that is) :-P.

[flavadave123]

i wish you would show us how to build your gadgets

[UltraViolence14]

wat about heat sinks ?

[FrigginSmift]

Its fires in pulses and rod doesn't generate any real heat

[UltraViolence14]

oh that makes sense

[laser5890]

it is a laser gun

[MBvolcom92]

haha thats so cool
