Hello, I am wishing to buy a c02 laser. I have looked around and I thought My best bet is COLETECH on ebay but then I saw this:

New 80W co2 laser tube water cool with power supply | eBay

I would buy this as it comes with a water cooler but my problem is that the length of the tube does not seem to be the amount stated, I am wondering if it is realy 80W. Any guidence? And if anyone knows what other things I should buy with this also please say.
Thanks.

Yes it looks a lot shorter than 1.6m on the picture, the most likely explanation is that they use the same picture to represent the whole product range from 10-100W.

You will need goggles, and since the light is invisible anyway you can just as well get as high OD as possible.

^Regular polycarbonate safety glasses work fine.

Judging from the electrical specs, that is an 80W tube.

Not sure if this is the case with this tube, but CO2 tubes can be rather fragile - moreso than other gas lasers (not sure where I read that?).

Wonder if anyone's ordered one before? :undecided:

Depends on what you want to do with it?

You will definitely need a beam stopper, I have seen ceramic tile recommended a brick may do as well.

Yes, I were not thinking. :(

Yeah, My house is made from wood, could be a bad Idea. Also, how can you tell where there focal point is?

I guess you put something in the way of the beam, then measure the size of the hole/glowing spot. :D

The raw output of the tube will not have a focal point. The beam will be divergent. To get a focal point for burning and cutting, you will need a lens that will transmit the long wavelength light. Usually lenses for this purpose are made from zinc selenide - ZnSe

You will also need a compressed air and nozzle system to blow smoke and debris away from the lens if you plan on using it to cut material in a CNC type application.

Cinder blocks and firebrick make fine beam stops. It's pretty obvious where the beam is hitting as it'll be white hot within a few seconds.

Thanks guys, Sooo, do you think I should trust the guy in the link or does anyone have any other websites?. I hate how the postage costs are so high, but I suppose it needs to be.

Having shipped some large fragile items over to the UK from the US I can tell you there's no way around high postage costs unless you happen to be traveling back from there and can take it with you. I would trust the tube to be what they say it is, although I wouldn't expect it to last terribly long. The quality is really variable on a lot of Chinese goods but for an affordable sealed CO2 you don't have a lot of other choices.

Aren't these lasers all in China? I was only using US to UK as an example of shipping long distances overseas.

Are you sure it comes with a cooling system? I don't see anything that says it comes with such a system. A self contained chiller would be very expensive.
