NEC GLG-3030 glass argon laser tube, pics.

That is the correct end as that's where the light sensor is.
I was thinking of maybe making a perspex housing for it so I can actually do extended runs with the appropriate cooling but seeing the tube at the same time.
Anyone know when these were manufactured?
Glad to see you're enjoying the pics.

That looks like a sp161b ignitor, was the original ignitor broken ?

Beautiful tube however, im blue with envy!

It's exactly that. The 161B ignitor is very simple to connect up. I would like to use the original ignitor to see if it works too, but I need to work out the connection wiring.

Love the argons with the glass end bells

Can't see anything on my Uniphase tubes except some purple glow through the ceramic

Hey all,

I've dug an NEC GLG3030 form the bowls of my garage and would love to get it running. If I can I would like to get an original power supply, so as to how to that would be well received.

Any alternatives to an original power supply would also be welcome.

Great photos, and great work on the 3030 shown.

Hey there!
Pics are coming as soon as I get a moment. I'm going to have to be quick with the camera as I don't want to run the tube too long without the fan.
Those 'bellows' things, I think, are to block out the room light between the tube, mirror and light detector. Maybe I'm wrong on that.
Don't you just love the thin bit of glass tube that's been coiled that joins to two ends? Real art! I wonder what that thin tube does.
I love the glow in these tubes when they fire. It's like the Aurora Borealis

The tubes "bellows" are to allow for fine tuning the cavity mirrors.

Connect positive to the free red wire and the start will fire the tube. The current then bypasses the starter throught the big choke thing on the start board. (am pretty sure). The negative connection is obtained through the filament, which is internally connected to the start board (one of the filament connections would have had a black wire coming off it to the start card. Here is a head schematic. Damn this bring back memories - Expermentonomen you are right

Where did you obtain the laser rob - looks suspiciously like the one I butchered up to run off my SGIL1. Did you get a home made brute force power supply with it, made with 2 x big toroids, a power resistor and some nice front panel controls?

Hi Ben,
I got the laser by chasing up an old lead from ages ago. I think they do something with printing equipment.
I connected it up to one of my NEC power supplies and an igniter out of a SP161B head and it flicked on first click. I had the same NEC and head listed on here for sale ages ago but with the little interest in it, I decided to keep it. Good thing too otherwise I'd have to put together a PSU for the GLG.
