There's a lot of really good technical material here but it's hard for the non-specialist to understand. (I don't even know if it means anything' let alone if it's correct). RJFJR 02:22, 21 Dec 2004 (UTC)
i.r. doesn't look like the correct abbreviation for Infra-red to me. RJFJR 02:22, 21 Dec 2004 (UTC)
I've done a lot of clean-up of the article and removed the clean-up tag. Those things that I can personally verify are now correct, but the article as a whole could still use a going-over by a true subject-matter expert. I've re-marked it as a stub; perhaps that will encourage someone who really knows to chime in here.

So far everything looks good to me. I'll see if I can't add anything more useful. I'm not a CO2 Laser Expert but I do know something about this laser.--

WHY BLASTING RESISTOR IS NOT USED IN CO2 LASER Vipan hira 14:43, 3 October 2006 (UTC)
The current revision of Carbon dioxide laser says "The CO2 laser can be constructed to have powers between milliwatts (mW) and gigawatts (GW)."; this contradicts the current revision of Laser, which says "Carbon dioxide lasers emit up to 100 kW". Neither article gives references, so can we please have some? -- Whitepaw 19:01, 21 May 2007 (UTC)
Sorry folks, the article still reads "continuous wave" and CO2 lasers are NOT the most powerful continuous wave lasers available. That honor belongs to chemical lasers, which achieve output powers at least an order of magnitude higher than CO2 devices. Free electron lasers are capable of powers even greater than that, but cannot be considered "continuous wave" devices. I know this to be true, as lasers are one of my hobbies, but I'll try to find formal citations later today. —Preceding unsigned comment added by 64.81.101.245 ( talk) 15:57, 26 November 2007 (UTC)
According to Carbon_dioxide_in_the_Earth's_atmosphere the principal absorption modes of CO2 occur at wavelengths of 4.26 μm and 14.99 μm. Why do CO2 lasers emit at 10.6 μm instead of these more natural wavelengths for CO2? There are lines at 10.6 in the absorption spectra I've seen for CO2 but they appear to be much weaker than the two principal ones. Some discussion of this discrepancy in the article might be helpful for readers wondering how the behavior of CO2 in lasers relates to its behavior in the atmosphere. -- Vaughan Pratt ( talk) 03:13, 20 July 2008 (UTC)
I appreciate the good soul's work who changed PMMA into "acrylic", but first of all, PMMA is not the exact same thing as acrylic. And just as importantly, PMMA is always used in micromachining, acrylic, well, I haven't seen it yet. However, if the person who changed PMMA to acrylic feels very strongly about this, I'll let it be. But the articles about CO2 ablation of PMMA don't mention acrylic. In the context of microfluidics and MEMS, the name "acrilic" is not used, though you will see, of course, (meth)acrylic acid etc. Blind cyclist ( talk) 21:26, 20 October 2009 (UTC)
http://www.gigaphoton.com/e/pdf/6151-126.pdf EUV lithography's source needs is a major factor pushing the development of high rep rate, pulsed CO2 lasers. Maybe this should be included in the applications section — Preceding unsigned comment added by 137.43.98.75 ( talk) 17:35, 15 April 2013 (UTC)

I've two suggestions. One is to note that "natural" lasing in Mar's atmosphere was observed in the early 1980s (and published). Seems sunlight pumps CO2 in the mesosphere and a 10% gain was noted via telescope. It has been suggested that on Mars, you could use a simple OPEN cavity - basically just two mirrors - which suggests that the section here on the need for "special construction" may be true locally, but not universally. Two is a request that this article should get technical. I don't mean concentrate on the technical stuff, but I'd sure like to have the (energy level) transitions that are used defined and described. 40.142.185.108 ( talk) 14:28, 2 August 2019 (UTC)
The most common quoted wavelength for CO2 lasers is 10.6 μm, presumably providing the highest output or efficiency.
The most common special wavelength in the trade is 9.3 μm, facilitating marking on certain 10.6 μm transmissive plastics.
Yet reading the neat isotope vs. wavelength table it would have us believe that the garden variety 12C18O2 lases in the range 9.0–9.2 μm.
It seems absurd that a special 14C isotope technique would be used in the VAST majority of all CO2 lasers to reach closer to 10.6 μm not withstanding the fact that the longest listed wavelength is 10.2 μm.
There is surely something obvious that I have not figured out but it is not clear from the page what isotope mix would generally be used to reach the most common wavelength of 10.6 μm in industry.
Could there be an error in the table?
