That was the plan - 3 mirror res - probably won't do anything tho. And yes current mode - the photodetector would otherwise send erroneous data to the psu :)

Wonder what the voltage drop across its tube was? I'm going to try experimenting with the omnichrome optics with the ILT - could be interesting.

Exactly - would have been a steal at the $150 I paid for it. Like brand new. :cry:

Coupla pics for ya: This shows the big hazmat stickers - theres a second one to the left. No doubts on it containing dangerous material! And heres the hours meter. What a waste :( edit: holy crap - thats a 33 hr tube - almost brand new. Even worse!

it was made in 95.

Mine were still there - on the opposite side of the tube to the gas reservior - big red and white stickers. I'll take a picture later when I take it out of the shipping carton to remove the useful bits.

I'll do the strip down later and bag it - thanks for the warning - I knew the stuff was dangerous, but only if you ground it up.

Your right - possibly in the back of the rubbish truck when the compactor kicks in. I'd better do some research into disposing of it. edit: that was easy - just fill in a form online and put it on the curb for collection on collection day. Just need to write on the box "HAZMAT - Beryllium...

It was the gas ballast. I had to remove the cover anyway as that was where I was going to put my tesla coil near to see if it ionised. The main tube was fine. Later I will carefully remove all the useful bits and toss the rest. I've got: 2 huge fans (lets make a wind tunnel!) 2 optics...

Sure did - seller watched my video and sent a refund and a very apologetic email - and I get to keep the laser. So I guess I now own a set of multiline optics, an ignite card and a frame LOL. :) So I guess this time I got what you would call a free ticket in the laser lottery. A few parts and a...

I know this is a double post. I open the box (in the video) and think to myself "This is gonna be broken. brace yourself!". I remained optimistic, and prayed to the laser gods to have pity on my new laser, but alas... YOU DO NOT PACK GAS LASERS LIKE THIS!!! I am not happy. I know I'll get a...

It was a joke Laserbuilder - the laser you put together at the university was in several parts. Thats what I would call a self assembly kit :)

Not only can you get parts for CVL's in your neck of the woods, you can also buy them as self assembly kits. I wonder if they ship to australia, and if customs would sieze it :P (shipping would be brutal) Well done mate :) tried to +rep you but need to "spread the rep" as I already +rep'ed you...

Re: omni 543-200MA which exciter? It will be a controller operated by an arduino nano. Since the voltage conversion tables are known and the pinouts, it should be trivial to have both current and light readouts on a 20x2 LCD along with status, and also be possible to emulate the real AR1A...

Rivem: ha! I've not done a build in years. This CVL project is amazing. LaserBuilder, you have done an incredible job building this thing. I'm so surprised I didn't even see this thread till now. Probably because I've been concentrating on ions :P 2.2-2.3kW in for 5W out, much better...

edit: I changed the topic title, so that gas lovers can follow my progress with this unkown, but photo looking intact, low hours laser head. I'll soon be on the lookout for a power supply for this Argon laser head. Unfortunatly, I've read the 643_Series_Master_Manual, (which includes the 543...

Mine go onto my home server (with 2 disk fail redundancy), which in turn is backed up to an LTO4 tape drive, and I store those at a friends place. As a bonus, I scored a pile of 55aH batteries and rigged them up in a 50v system to power a monster UPS - which basically means the power has to be...

I have a similar set of glasses (wearing them in my profile pic). But I beg to differ with you. You should NEVER look into the beam of a working laser, no matter how low the power. Thats just asking for bad luck - what if the power supply went bonkers, supplied 20A to the tube and it jumped up...

I'm not sure, however it wouldn't hurt in order to have evidence handy that shows you didn't cause the damage and it was damaged in transit, or from the outset. Of course if you get screwed by PayPal, theres also the option of credit card chargeback - but this will screw you with PayPal - you...

Great - I'll try the bbq thingie first then I'll go for the tesla coil. At 13 watts it shouldn't cause any problem but to be safe I'll still disconnect the starter/light feedback board and move them well away. I'll wait till I get the tube - I read these have a glass end bell, so it should be...
