The CO2 Laser

By Derek Kverno and Jim Nolen

    The Carbon Dioxide laser is one of the most useful and important molecular lasers because of its high efficiency (up to 30%) and intense output.  Since it is capable of providing such high, continuous power levels it is used extensively in industry for cutting and welding. The study of the Carbon Dioxide laser is also a popular experiment because it clearly demonstrates the characteristics of a molecular laser and the dynamics of molecular vibration.
