Default Budget CO2 lasers?

I've been looking into a way to get into high power (>20W) lasers recently without much luck, so I figured I'd go ahead and finally make an account to ask you all.

I'm working on a home experiment that involves burning a small amount of material at a high temperature in a vacuum chamber. A laser would be most ideal for this, but I'd need a significant power level. This is also a fairly expensive project without the laser, so I'd like to keep costs at a minimum. Diode and flashlamp pumped lasers could probably do the job, but a CO2 laser was the first thing to come to mind.

Do you have any suggestions on minimizing the cost of high power lasers? I'm fine going for used or just parts. I know people have been able to get the necessary parts free from medical facilities, but I don't expect anybody in my area to have old enough systems to retire. Would it be cheaper to go another laser route?

Default Re: Budget CO2 lasers?

Well I have never heard of what I would call a budget CO2 laser, they are also quite large. How large is the vacuum chamber? Will the laser be inside of it? Or outside of it? What is the vacuum chamber made of?

A cheap CO2 laser from China is probably your best bet if you want to go for CO2 - maybe see if you can find something used on eBay. Alternatively, you could try the buy/sell/trade section here or on Photonlexicon.com to see if anyone has anything.

Keep in mind, you'll need a window made of ZnSe or NaCl so that the light from the CO2 laser can pass into your vacuum chamber - borosilicate glass and most other glasses won't work at 10.6um. I don't know how well either of those materials would hold up under pressure - I imagine ZnSe would do fairly well, you should be able to look up the specs on ZnSe laser windows to find something that'd suit your needs. The other option, if your chamber is big enough, is to put the laser inside of the chamber. That may cause other issues though - CO2 lasers often require water cooling for one, so you'd need to run water into the chamber somehow, as well as power for the tube. https://www.lasercomponents.com/de-e...or-co2-lasers/

A high power fibre coupled laser diode at ~800nm might be a good option - regular borosilicate glass has ~90% transmission at that wavelength. Fibre coupling would allow you to get a relatively round and even beam too. CO2 would be good for the same reason i.e., a fairly round and even beam.

What's your budget?

Default Re: Budget CO2 lasers?

Laser will be outside of a steel vacuum chamber with the necessary IR transmissive window. The target will contain material backed by refractory ceramic. I'm not looking for anything fancy or heavy duty though. I figure if the Chinese can sell 40W laser engravers less than $400, I may be able to get just the laser components at a decent price. I'm just looking for the lowest cost.

Default Re: Budget CO2 lasers?

Something like this may do you then:

40W CO2 Sealed Laser Tube 850mm | eBay

Would still need a power supply and some water cooling equipment to go with that.

Ships from the US so that's always nice. Probably still cheap Chinese quality though.

Another possible solution: Laser Diode Pumping CW BAR Coherent FAP 25 Watt Burn High Power | eBay

Several members on here have similar diodes, perhaps someone would be willing to part with one? Again, you'd need a driver and some cooling for that too. And of course, laser safety glasses. That kind of power (either from a CO2 laser or a diode) is serious.

Thanks for the input.

The plan is to use a ZnSe window if I go this route. It should almost definitely meet specs. The chamber will be small, so laser has to be outside in the gas route.

I've looked at the fiber-coupled lasers, and they seem like they may be a decent option as well. I'm just not sure if the CO2 will be a bit lower cost or not.

Budget is somewhat flexible, but ideal would be less than $200.

You *might* be able to get something used for that budget, but that's really pushing it. I seriously doubt you're going to get anything new for that kind of price though, even from China. The cheapest I can seem to find a new 40W tube is about $250-300 - without a power supply or anything else. A certified pair of laser safety glasses can cost nearly as much as your entire budget.

See if someone drops in with any other suggestions or perhaps someone can sell you something that fits your budget.

Problem with the bar diode arrays is that the beam profile without any correction is absolutely horrid. Fibre coupling them yourself isn't really practical either. So depending on what kind of beam specs you need you'd have to go with fibre coupled - or get some optics to correct the beam somewhat.

This video may give you an idea of how the uncorrected beam profile looks:

That's what I've found. Just want to see how low I can get the cost. I definitely don't need new, and the system should be self-contained, so I'm not too concerned about high-end safety glasses.


I know how the bar diodes are, and I don't expect to use one without fiber coupling. There's no way I'm getting that beam profile through my window without the fiber. It's only going to be about 1 cm diameter.

What do you reckon is the minimum power you can use?

Hmm, I may be able to help you out then. Let me look through my parts when I get home.

Also, seeing as you can go that low - one of these might work if you can still find one: RF CO2 build

You can get a 20W co2 tube that's 45cm long , they show up on ebay now and then , I paid 150USD for a 20W tube & PSU .

On the goggles side of thing , cheap 50p polycarbonate work perfectly well against co2 lasers , Nothing else ONLY co2 lasers .

That would be ideal. Thanks for the tips. Is there a particular seller, or are these just used systems that tend to pop up?
