Default Argon JDSU 2214 ML help

I posted this on PL as well, but felt like it should be put here too. Any help would be much appreciated.

So i have everything wired up correctly, but when I power up the laser, the only thing happening is that the plasma tube glows, followed by a weak purple light coming off the aperture. I tried to adjust the power with a pot as well, no difference. I was told that the laser is misaligned. I paid oveer $550 for the whole setup, so I would really do whatever I can to get this laser working. It's my first gas laser and was like my dream to see the colours, especially of a multiline tube. I hope you guys can help. Thanks in advance.

I had a tube like that om my collection, which was new old stock. Most likely, it was sitting around for years without being turned on and that's what killed the tube.
I don't think that model JDSU tube has mirrors that can be adjusted either. Mine certainly doesn't.

No mariomaster sent this laser to silvershot 100% working as far as i know, so something must have happened during shipping?

If the plasma is igniting, but it is not lasing, there are really only a couple of possibilities. Either the tube is worn out or the mirrors got knocked out of alignment.

If it was working before it was shipped, then it could only be the mirrors. IMNHO it takes a pretty hefty smack to knock the mirrors out on these tubes. This is even more true if the laser is padded and packaged well.

The bad news is that re-aligning the mirrors on these tubes is not an easy task. The even worse news, I have never been successful at realigning the mirrors on one of those tubes. I don't even try any more.

We would have to see the packaging to know if that was a contributing factor.

Peace,
dave

Not sure if 2214 heads have shutters, but if it does - check that is fully open. I had a head one time that had the shutter partially closed, I could still see a purple glow - but there was no output other than that.

We covered this in PM. The discussion over at PL is a bit farther along.
