Dafuq did i just buy?

can someone shed some light on this piece and what it might be worth?
I got it for 220 euro, didn't test it, but it doesnt smell funky and looks great inside




Check the imgur album for photos

argon laser with pcaom modulation and scan head.

hahah this is funny, i found a thread here from 2008 about exactly the same laser...

Wow! I've said that more than once in this silly laser game!

[db3306]

Do you guys know where i can get a psu for the pcaom?
This one went up in smoke. And it was smelly. ��

Nice deal!, is that little silver block heatsink red module?

[db3306]

not sure what little silverblock you mean, but this is the red module, i need to change it btw

Heya db -

Do you guys know where i can get a psu for the pcaom?..

..Do you need the entire NEOS Driver? (..looks like this unit..



..Or, *just* the actual PSU, for one? (..the 'silver-cage' one, far upper-left, inside this one..



..Lemme know, I can fix ya up with either one.. And I'm packing / shipping a parcel to the UK, tomorrow.. what's one more to Sweden?

cheers..

It should also be noted that the ALC 68 is not your usual run of the mill <250mW argon.

There's a chance that this could do multiple WATTS. They've been known to crank out serious juice.

Quote from the Laser FAQ:

Sometimes, ion lasers turn up that are about the size of a typical small air-cooled unit but have CDRH power ratings of multiple WATTs. In most cases, these are lasers designed for low duty cycle applications. Both the power supply and cooling will be way underrated for CW operation.
(From: Steve Roberts.)

For CW work, 4 units of 350 cfm Patriot fans for a model 68B, the HGM5 is an ALC-68B with shortened Brewster stems, a bigger gas ballast, and a slightly wider bore, it can be 3 watt CW laser, but is usually ran duty cycled. I have seen ALC-68s do 7 watts on the bench when freshly made. The HGM does run about 500 mW CW and can be pulsed up to 3 watts max for up to say 15 seconds with the existing HGM fan, which is a big squirrel cage type.

The warning label is 5 watts on the HGM5, the medical circuitry clips the power at 3 W.

If you could cool it enough, an ALC-60X size tube can do 2 to 3 watts easily, in fact there is a medical unit that uses a small internal mirror tube at 3 watts using a closed loop water-to-air-cooler in a power-on-demand application at a 5% or so duty cycle. What limits you on an ALC-60X is the glowing red undercooled anode that will open up when you try it - spoken from experience, not conjecture. :-)

wow, how do i know what model of the 68 i have? would be awesome to crank it up
My biggest problem at the moment is to get the power to run it haha. I guess my biggest chance is to fire it up at work as i only have 16A at home.

The cooling is a squirrel cage blower with 2 air intakes to the laser and a smaller squirrel cage blower to get the heat out.
