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 :)

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! :rolleyes:

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?

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

..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..

Attachment 44775

..Lemme know, I can fix ya up with either one.. :cool: 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.

(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.
