Greenhouse gas footprint when they breathe and plants use it for photosynthesis. Carbon dioxide is released naturally by decomposition, ocean release and respiration. Humans contribute an increase of carbon dioxide emissions by burning fossil fuels, deforestation, and cement production. Methane (CH) is largely released by coal, oil, and natural gas industries. Although methane is not mass produced like carbon dioxide, it is still very prevalent. Methane is more harmful than carbon dioxide because it traps heat better than CO. Methane is a main component in natural gas. Recently industries as well as consumers have been using natural gas because they believe that it
Carbon dioxide laser Carbon dioxide laser The carbon dioxide laser (CO laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964, and is still one of the most useful. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO laser produces a beam of infrared light with the principal wavelength bands centering on 9.4 and 10.6 micrometers (μm). The active laser medium (laser gain/amplification medium) is a
