Smallest CO2 you've seen?

If you're gonna make a CO2 laser you may as well shoot for more power because the difference in cost of materials for a 100W tube vs a 25W tube is small. I've been wanting to build one myself but have been stuck trying to acquire suitable optics.

As for the cost, a lot depends on what you can scrounge. Also a home built laser is likely to be much more fiddly and unless you've built them before, you will probably be a lot better off buying a commercial tube if you want to put it to real use.

For example, there are also tubes of 4W, 250mm long (9.84")

And in that claim they can produce tubes from 1W to 80W

But in this old threads already talked about this.

Thanks piferal, LInk 1 is dead though, i tried link 3 and went to buy now and it basicly came up with a ebay style listings and there was only an 80w listed for 250.

I checked out the last link to the forum post but since it was 2009-2010 dating had figured he'd sold all of them, and as pointed out in the 2nd to last link, it would be best to get a little more then you want for a similar price and just decrease the current to reduce power and then if need be increase to desired levels, provided the psu has adjustable current.
