A flash lamp pumped dye laser with over 50 joules of highly collimated, 580nm light is described and demonstrated. Damaged lens at 13:38 will be shown with better lighting in the next video.
What happens when passion meets talent and a reasonable amount of funds. Impressive sir, makes me want to go back to school.
I couldn't stop laughing at the cameraman. Great science.
This guy is sharp, and a top rate show off. I love it.
Well I'm just totally in awe of you guys! Thanks for taking the time to put this on youtube.
No problem! It's a lot of fun and thanks!
Wow you are still alive guys! and have not been killed by HIGH VOLTAGe laser capacitors... or death beam!! that's great to have you back again!
As usual; a very impressive lesson. I hope you don't mind me referring to these videos as lessons.
The camera man isn't the only one who jumped. I certainly did myself. Thanks again, great job.
Nice to see some new content. You didn't mention the power output at 25%, but based on the 16mm vaporized circle of ceramic, I'm going to assume it's relatively high.
Amazing stuff you produce here! I can't imagine the dedication you have, to get such great results you must have greater focus than your lasers!😁
Cool...you must try a moon bounce with that
monster.
"So what you're now seeing is a terrified cameraman" @ 14:36
Great, can't wait to see this series continue (already saw the existing future videos available at this time) :D
The closeup of the ceramic plate on the end wasn't very good, I wold expect better from you, but otherwise, you are genius. Thanks for your dedication.
Great work! Wish I had one of those in the garage. What's with the hotspot in the beam profile? ;) ... but seriously... I wish I had the patience and space to build one of those. What's it for and what is the FWHM of the pulse? I'll probably watch the other videos now to find out. I've got 10+ years experience in laser flash photolysis, developing transient absorbance spectrometers for research and commercially. Doesn't look like you need a hand with...basically anything. But should you ever, let me know. I'd be honored. Best channel on youtube!
Thanks!
Awesome video. Most of it was way over my head but I feel smarter for it nonetheless
Very good demonstration and discussion, even for someone like me with just a casual interest in the subject. It seemed as if the camera operator got a little shook up when firing on the first set up. I would imagine being near such a discharge in person is much more dramatic that it may seem on a video. Interesting stuff and thanks for a good video.
I have no idea what most all of this is but I hope you end up doing more laser videos.
great job! your cameraman might want to read up a little on manual camera focus for those shots with the protective goggles. :)
Use to shoot the smartphone camera, in my experiments with microwaves, and equipment that generate high fields, disrupt the focus.
legendary! xx
Here is a question, how do you deal with the rhodamine? I used some for a school TEA LASER project, and it was such a mess, it got everywhere, now four months later I am still finding stains.
That is definite skill set. You have to pre-think each step with layers of disposable protection and trash receptacles readily at hand. Also, if you have alcohol at hand, any spills or splashes can be diluted/wiped up if you flush the stain IMMEDIATELY and I mean IMMEDIATELY as in less than a few seconds.
If he goes nuts one day we have a Big Problem. so give him Love, an to the camera man !
Awsome work as usual ! Well done, Well explained !
Not a drop of Dye anywhere...remarkable...just thinking back to some of the university labs ive worked in !
Been there...done that, but not this time.
Mr. TI addresses this in a question by Joseph F, above. I’m just here for the bangs pops and jumps of the cameraman attesting to the true power being demonstrated, so I don’t understand what the problem with the dye stains is all about. But when I saw this comment I remembered the comment above. It was “2 years ago” and your comment is “9 months ago” so, I guess 15 months before you?
I have found a channel of physics porn.... excellent work sir, excellent.
Same Here! Anything from physics to distilling... usefull information without the clutter! Thank you for a great channel Tech Ingredients!
Snow in April? Thank's for posting, missed you.
14.46. nice shot
How short short is the beam? What kind of lens and coatings were damaged?
Always great content 👍
you're back! :)
Can you post plans? for even a fee? I have a HUGE argon laser head that is beautiful but bad tube. I got it free and it is an old Coherent Graphite large frame head that is 6 feet long. I want to build something out of it. I have been told how it CAN'T be done and how stupid I am trying. . I need someone that will encourage me. I got plenty of DPSS and flashlamp ND YAGs but I want to build one of my own. thanks for any help this video is awesome
Those lasers have a long history of aftermarket refurbishing. They require high vacuum skills, excellent optics and precision alignment due to their low gain. The power requirements are in the 10's of kWs and usually require 480V, three phase power. Nevertheless that has not stopped many people from rebuilding them. You might want to visit:

The community there is very supportive.
Oh, and thanks!
Thank you for your reply Yes I have a working 10 watt Ion laser and I have to go to my friend's factory to run it as I installed a 600 amp 480/277 service, and I run it there. I got that one for free from a college in Columbia Mo. it works but this head is orphaned and no power supply I LOVE the way it looks and would love to make something out of it. the tube is busted at the water inlet part and looks like it happened when it was running. I basically wish I was like you making real stuff like projectors and such. but I will try them guys the laser pointer forums are are bunch of nasties for the most part.
That was seriously impressive!
What kind of damage would it do if you were to put your hand in the way of the pulse?
I like your videos but you need to take a Laser Safety class. The LIA has some good online courses. I am a Laser/optics Technologist and have seen people blinded and severely injured doing these types of experiments. Not trying to give you a hard time, I'm just concerned.
dude im laughing my ass off @ https://youtu.be/vNby-VcR5FI?t=840
"But what you're seeing is a terrified camera man"
whispers "Stop"
HARD CUT
This is my favorite channel. thanks for making all these great vids
Have you ever tryed pre warmed collimator lenses ? ;-)
It reduces the thermic stress, and the conductivity !
No I haven't.
@@TechIngredients : Try it with a hairdryer.
I had effects from 50°C upwards.
Normal standart lenses from optical glas, will withstand better at high flux ...
No high end lenses needed in my case.
Don't suppose you'd make this more YouTube-friendly by using a slab of pork as a target instead of a ceramic plate ;)
The people demands to know if this can be used as a weapon ;)
so let build a annular laser array aimed at a ruby Crystal and use lasers instead of flash tube to make a mega laser
"throw away the used stuff" can be patented? wtf
I think it's more of the method of throwing all of it away so you have zero dilution effect.
The fluid flow control system is what was patented, not just the idea of "don't use the burned up stuff again"
Though to be fair, Amazon has a patent on "only having to click once to purchase something" so it probably is possible if you word it well.
Exactly what I was thinking 😂
I shot a hole in my right hand with a >5kw cw laser ....
Had to hold my hand still, till a friend hit the emergency off otherwise would lose my hand/fingers.
Friend was told to fire the red adjustment laser, NOT the loadet Co² ...
From this time, the key of the Co² is in my pocket.
Realy a PAINFULL day for me.
Thank god i did not lose my eyes, no safety googles for the Co² ...
PS: Not the pain is in my memory, only the stinking, burning meat !
Wow you should really explain more. That's one hell of a story.
What part of your hand? How big is the hole? How long did you hold your hand there?
What did you do to your friend after? Was there any permanent damage (not including the hole)? I mean can you still use your hand?
@@peoplezk1 : Hi !
This was the worst moment in my life.
Holding my hand 5-10 seconds in place, cant remember exactly.
The hole was like a penny, but after 2 operations you can 't see that it was a hole ... normal scare.
NO blood at all from the "shot" !
Pain AFTER aprox. 10min.
Hand works like new !
My accident was in a German heavy metall company.
14:35 Your camera man needs to drink some concrete and harden the fook up. Judging by the lack of camera focus the laser scared the crap out of the camera too lol
Dave I think the camera focus had to do with the goggles put over the camera lens
@@oddjobbobb put it in manual focus then.
I have a green pen laser. I was told to stop pointing it at airplanes.
I hope you stopped!
Love the modest mouse intro but it doesn’t really fit the graphic at all lmao. Let me guess, that was your sons’s input?
You guys have a tendency to place laser outputs at head height, it is a BAD idea.
cool video
Thanks!
If there should be a fire, the carbon dioxide tank and the oxygen tank will get into an epic battle. If its safe outside, i am rooting for the oxygen tank.
put cam on surface so I can see the device without blur please!
But what are you doing with the laser? What are you using it for?
I am interested in lasers per se. Dye lasers are powerful, remarkably easy to manipulate and comparatively inexpensive.
Holy SH#$BALLS
Now make it hand held...lol...
What practical purpose does it serve?
It's funny that you have a scared cameraman, keep folks wondering about you, never evr let anyone think you are harmless.
No one thinks we're harmless, just the opposite.
We're continuously allying fears.
I used to really be into this kind of stuff in grade school, never got past proof of concept and was always discouraged. It's only with hindsight I realize it's that I scared everybody that took me seriously! The rest just thought I was babbling like Jimmy neutron because they didn't understand what I was talking about, and I didn't realize as a kid that they were the ones that didn't know fact from fiction.
Jumped on that Scientific American TEA laser when it was first published...
@styropyro - 2017-04-19
50J output from a dye laser??? DAMN. Even more impressive that this isn't at a university with millions of dollars of funding. You have to be approaching a record here. Very cool video as always.
@RedShiftedDollar - 2017-04-29
styropyro When are we going to see the Stryo-TI collaborative project? That would be epic!
@adamshine5 - 2019-08-13
agree'd!
