Back when I was a laser pointer enthusiast, I was in a forum where several of their members collected ion lasers. These things need to be turned on regularly or else they die. Not so bad for argon ions, but HeCd lasers required about 24h turn on time distributed along each week to not die, and some were even worse. There was a guy who literally heated his house with the lasers, and he had about 20 or 30 ion lasers. Poor guy got broken in and the burglars broke most of them and had to sell the remaining ones.
That's one sexy af PSU! ?
Looks very much like an scr controlled rectifier supply and looks fairly similar to some of the old DC motor drives + cross an early 1 or 2 kw power amplifier.
Might be a nice projekt to convert der passtransistor board into a big ass electronic constent current load. The transistors are already in a cc configuration, hack a control pot and a meter across the shunt in there, add a water cooling pump and an old watercooling or even car radiator…
Powder may be zinc oxide from the galvanizing of the steel. And it did that due to humidity.
I've dealt with several permanent laser shows around the US. we had a pair of Coherent 80w krypton/argon white light lasers. Their product is second to none!
Is that AvE in the photo behind you?
Fun teardown!
What would StyroPyro have to say about this ?
I think I can make ALL the cats in my neighbourhood go crazy with that lazer..
I think the white powder is Aluminium oxide
Sell it to Iranians
What powers the power supply lol
Can you advertise on the moon? It was thrown out wow? please remove the sign i find it offensive to my life style =(. Turn off laser before opening fuse holder you know what a Fwit would say to that "challenge accepted". Can i blink fast than light lets find out. I guess this is why i do not have one of them lasers. Whats the law on owning that? Charge them caps up throw them to people and say think fast! see being an fwit has some perks.Would that of been assembled by lightning gods or just an assembler in some shed?
I could imagine big magic smoke out of that, but maybe not. I wouldn't want to repair those.
But I want to see inside the Laser tube housing, I'll bet its gorgeous. I have a 1W unit from a microfiche writer and its cool enough but that is something else
16:15 That is called Cocaine, Dave.
For the comparison on newer lasers – 10 watts must be 10 watts. If one is more powerful, one must then have been meassured wrong. – Right ?
@16:25 – I believe that is Aluminium Oxide.
Hello from the Czech Republic! 😀
WOW !!!
WONDERFUL !!!
PLEASE OPEN LASER BOX.
Thank's.
I still use one like this, but slightly older Zeiss. One thing about this type of laser – there is absolutely no way to shift the lines and they are extremely narrow. When I need to double check my equipment alignment there is nothing to replace our trusty old argon laser. And due to it's purity it's easy to filter it off, so it also works well as a source of excitation for some of my materials.
repair and power it up! EEV Lab seen from space! lol
the wires coming out of a bus bar beside the fan at time stamp 30:20 has the colour code like the resistor colour code… brown, red, orange, ETC..
the block diagram for the power supply looks so simple..
DANGER not to be operated be fuck-wits… cool sticker on the front of it : )
Not to be operated by f*ckwits ?
16:17 Very powdery and it gets everywhere. Like the sand on Tatooine.
I had an orgasm when I saw all of those TO-3 MJ15022 power transistors..
MJ15022 about 10 each original and 4 for new copy unbranded
27:50 As you can see they are 1% which ordinary resistors of this wattage are not but 5% so yes they are bought for current sensing as well.
An Argon-Ion Laser is principally a water heater, that outputs a little light as a byproduct.
i want those golden power resistors. they are cute lol
