Remember to exercise those argons!

Yeah, I need to fire mine up as soon as it gets cold here. It has been since last March since I had it going.

I got mine new argon running for 2 hours today on 15.3 mW @ 6.5A:evil:

 

[ultimatekaiser]

Nice, Maybe I'll drag out the massive pile of stuff i need to run my whitelight tomorrow. I probably should.

 

[paul1598419]

Which Taipan OPSL is that in your avatar, Matt? It looks like the 532nm, but that 577nm does look green with cameras at high power.

 

[ultimatekaiser]

off topic. but it's a green one. The yellow one shows up kinda more like 561-a funny yellow green. A friend of mine got a pic of his, and it shows up yellow. The camera I usually use just doesn't like it.

Just switched off the ILT after a few hours run at 6.5A. Got a bit cool this afternoon, and it needed some exercise and I was at its location up north.

I just turn on the power point, pick up the remote, turn the key and it fires up first click. Still spooky the way the fans work on these (they don't come on until a certain temperature is reached). I have mine doing a liquid sky effect, and half power is plenty for that. It utilises a polygon scanner to achieve the effect.

Once I rearrange the house a bit, I'll have a permenant spot to do electronics and play lasers. Right now my workbench is a mess. So the ILT lives where it can get some use, under my supervision of course (I bring the umbilical and key home when I'm not visiting my friends property).

I don't run my Argons often but when I do, I let the cathode heat for about 10 minutes
before I power up. My ML02 Lasos gives me 8 lines using a CD. It has "rested" for almost a year and light right up. Let the cathode get hot before you slip it the meat!

Running my JDSU2213-15VL with my soviet power unit from a large-frame argon laser. I hadn't the cooling fan at that moment so I turned on this laser only for a minute or two. The tube voltage drop is 260V, the current is 7-8A. Are these values normal for this laser head?

Is that a rewound microwave oven transformer I see running the filament?

 

[Laserbuilder]

Yes, it is.

 

[vk2fro]

Those transformers do have their uses once you hack off the dangerous 2kv secondary

I saw one on the street the other day and meant to go get the transformer. Its probably been picked up by now by the council.

 

[9A3DAA]

Yes, it is.

Can MOT give enough current to laser filament?
I know magnetron from microwave need 3V 10A

 

[vk2fro]

Depending on your filament voltage, a simple rewound mot can power a filament easily. The battery guys often repurpose them as spot tab welders. Once the HV secondary is hacked off, they are a cheap (free) source of gobs of current at low voltage.

From memory when I saw the video of Photonicinduction destroying a perfectly good argon, he also used a mot to power the filament.

Yup, a rewound transformer will power a filament no problem.

Usually somewhere around 2.5-3V at 20-25A for the small air cooled heads.

Continuing to tease my 2213 15Vl argon head. Today I ran it on 10A and saw that it emits 2 close lines, a 457 nm one and possibly 454 nm one that was much weaker. When I tortured it with 15A -- 488 nm line appeared, mostly from the rear side. At 20A all lasing from the working aperture ceased, but 488 nm continued to flow from the butt of the poor laser. Than I continued to run it on 10A for a while.
