WOW -- Rock salt windows!!! It's been years since I did that with a homemade tube.
A lot of work but rewarding. I didn't have the benefit of a HeNe to help allign the mirrors back then and the 15,000 volt PS was a terror.

I bought NaCl (unpolished) lenses and I think I still have a couple.

Well - I'm been experimenting with different setups. My first setup used a cold cathode fluorescent lamp tube from inside a flat screen monitor, with a clear polycarbonate tube lamp guard for the water jacket.



However, I decided to discontinue it. The tube was only 1 or 2 mm ID, and it was too hard to manage in this form. Alignment would have been far too difficult, keeping the tube perfectly straight was a problem, and the hole through which the beam would pass would have to have been too small.

Next, I started working with this larger design:





That one was made out of 2 fluorescent lamp tubes. One tube was narrower than the other one. The wider one was placed around the narrower one, and was terminated at it's ends with PVC end caps. The narrower one extended out past the ends of the wider one, and was terminated by copper electrodes. The wider tube was used to serve as the water jacket. Here is a better view:









Last night, however, I accidently broke this tube
So now I am beginning once again with a new design. This time I am experimenting with longer tubes. Here is another low pressure air discharge (which is what all of the previous pictures show) in a 5 foot long tube!





So my next design will use a longer tube, although shorter than the one shown in the picture above. I hope this time I can complete it without messing something else up

Would be a flowing-gas laser-tube right?

Basically, yes. But I would like to flow it slowly, or as little as possible if I can get away with it. I can't afford to 'burn' gas.

A TEA CO2 laser would be kinda cool!
Yes, it would. In fact, it would probably have higher gain than a CW laser, and might therefore be more forgiving with regards to optical quality.

It was long ago but as I recall, I used jewler's polish grit mixed with concentrated antifreeze -- no water -----
Polish the crystal on a flat piece of glass.
My tube is 3' long - glass in glass. PVC is too flexible as I recall. I still have that tube with flex mounts for the lenses.

My first ruby laser used a hole in the silver coating on a normal mirror. With CO2 lasers, this is an easy alternative to expensive OC mirrors that are made of one of the few materials that will actually pass this wavlength. Hole-couplers are not best, but they work where better alternatives are not avaliable.

Here are my sets regarding experimental mirrors with my ruby laser:

You can click on any individual picture for a description which I have provided for some of these. If anyone cares to look at all of my sets, they can be found here:

I've experimented with making my own copper mirrros.

However, I just took some craft copper and polished it with this stuff...

When using Jeweler's Rouge, however, I find that I actually scratched the copper to some degree. Is there a type of polish that will produce a brilliant mirror-sharp reflection in copper? I need to know. Making my own copper mirrors for future CO2 projects will not only be cheap and convenient, but rewarding as well.

I'm a real amateur, as anyone will discover when browsing my flickr photos. I make nearly everything from scratch. No high-tech stuff over here. I tend to do a lot of trail and error experimentation - I have only a very basic understanding of electronics. That's one of the reasons why I use electrostatics for so much of my work: it's a technology that even I can understand

That's even better. The rock salt windows are what I bought the jeweler's rouge for in the first place. As is, my rock salt window will be a little like shining a laser pointer through a glass shower door - the output will be a mess, but it should still be relatively concentrated at a short distance, and should still be able to be focused. But yes - I would love to find a way to polish my homemade rock salt windows to a smoother surface. Any suggestions that you have will be greatly appreciated. I want to make this laser as much from scratch as possible. Too many ready made parts kill the fun for me - not to mention my budget

Rock-salt window...exzessive DIY :-) I wouldnt try that, but I love the fact that there are people like our Jarrod.

I would use at least a set of CO2 mirrors ZnSe for example. Would cost a few bugs, but today I would not call them expensive anymore.

For the tubes: I would cut some aluminum-electrodes / tubes holders and use some o-rings and screws for sealing.

0.2 / 0,3 microns may polish very well almost any material, as the professionals uses it for gems and stones .....

Just an idea, anyway ..... don't really know how it can work on soft metals like copper .....

You are correct: the beam divergence and overall quality will not be good. The performance will be worse as well. But for a DIY system from scratch, it's a start.
