The A-14 is what I used in one of my old HeNe pointers I built for a friend. I had it set up with a 6" tube that did about a milliwatt, so I had it configured for 9V in and an output current of 3.7mA. I just set it up to use 2 18650s in series. I should probably find someone who can make me a...

Voltex is in my backyard and they make some of the best HeNe supplies you can get in my opinion, but they are very expensive. They actually make a rather unique universal power supply for HeNes, which I actually have been planning on doing a review of, but it's not here yet. I've used one of...

Yeah used to have a cylindrical one that is intended for those little 6 inch tubes and it hugs the back end mirror and is actually a pretty snazzy little thing from Melles Griot but I think voltex makes an equivalent. I’m not sure what I did with it. It would be great for that though

Very cool. I been thinking of buying some of those little cylindrical supplies and making a pointer out of some of my little 6" tubes. maybe I should take one of my oranges and make something similar

Agreed. I posess all the requisite equipment and knowledge to test it. You need only pay for shipping. I can also sell you a power supply if you so desire, which would greatly increase its propective value if it is healthy.

The 1145p is roughly a 4kv 6.5mA hene by spec when new. 21mW of red iirc. Power supplies for them are pretty expensive. That laser is pretty expensive if it’s in good shape, at least in theory. But most of them are well used by the time they hit the trash. You’d have to prove it is working and...

If I recall correctly that’s one of those little 6 inch siemens tubes correct? It probably won’t require all that much. Probably around 1200-1400v at 3.7mA or maybe 4mA. Somewhere in that neighborhood. how are supplies for tubes that small are a little harder to find, but they do pop up fairly...

I should probably sell my regular argon....I basically never run it anymore and it should probably go to a good home

If it’s the same as mine, it’s 670nm diode at <1mW. Mine does about 0.8mW. They’re pretty old, very early pointers. Mine’s still in the box too. Though I’ve used it a little. They’re not all that bright since it’s pre-635nm diode days, but the laser‘s red dot is a nice deep red little pinprick...

Glad it got worked out. Enjoy! Maybe I’ll pull my Brewster out one of these days again too.

I can relate. they make great heaters. I haven't fired up mine in ages. Ultimately small air cooled argons dont care how long they sit though as long as they're not leaky in my experience though. It's only large argons that have gas replenishment need running to keep the gas pressure under control.

That’s probably the best course of action. If you’d like to talk to me at length about it you can reach me on removed pretty easily if you have it. I’d be happy to chat and share some know-how.

Its no problem. I haven’t really been around all that much, as most of the crowd that I used to spend my time with on here have pretty much all left the forum as times have changed. I’m still around time to time though, and folks like Diachi know how to get a hold of me if they need me, so I’ve...

No sources needed. I’ve done it. So I’m speaking from experience. I’m basically the HeNe guru of the forum. and I do agree gas lasers are definitely my favorites for their cool factor and history. I don’t have much in the way of single diode lasers. A few...plenty of dpss ones tho. As for opsl...

Absolutely. It’s been along time since I’ve seen someone post in the gas section. I’ve been pretty lonely over here! I just randomly logged in today and saw you’d shown up with a gem. I’m happy to help make sure that it ends up nice and happy. I should probably email REO about getting a...

Yeah I would definitely run it it it’s rated current first. They scale pretty well with current. If it was low pressure it would drop out pretty fast because there wouldn’t be enough buffer gas to keep it going. As the tube warms up it would create a negative resistance and I would basically...

I’m actually wondering if you bought Sam‘s old weak tube. he had one up for sale recently that was pretty we and only did red in a tiny bit of orange.

It appears to be missing the dust cover. (Or maybe your model just doesn’t have one) they get dusty pretty easy, And the tiniest bit of dust or scratching can really mess these up. The become misaligned pretty easily too. The color looks good so I’ll be willing to bet that it probably is either...

I’d be interested in one. No particular wavelength in mind though. :)

Honestly it’s very hard to pick. I like 500.5nm, but i love 577nm and 612nm alot as well. I also have a fondness for the classic 694nm from ruby
