Abstract : A review of the CO laser is presented. First, a brief review of the general operational characteristics of a CO laser and the principle of partial inversion is given. Then the principle of anharmonic (V-V) pumping is presented. A state-of-the-art review of the various types of CW CO lasers is presented together with the excitation and inversion mechanisms of these CO lasers. These include the following: the electric CO laser, the CO-N2 flow laser, the CO, GDL (gas dynamic laser), and the chemical CO laser. Finally, a recently proposed CO GDL pumped by an electron-beam (E-beam) ionizer-sustainer discharge system is described. This new laser system could have both the high efficiency of an electrically pumped CO GDL and the high power of a thermally pumped CO GDL because of the unique operational requirements of the CO laser.
