Experimental determination of the saturation parameter of a cw electric-discharge CO laser

È. N. Lotkova, L. Ya. Ostrovskaya, N. N. Sobolev


Abstract: The following parameters were determined for a cw electric-discharge CO laser, using a mixture of CO–N2–He–Xe–O2 for both continuous-flow and sealed-off operation: the saturation power Ps saturation parameter Is unsaturated gain, internal optical losses in the resonator, and ultimate power extracted from unit volume of the active medium. The dependence of Is, on the pressure of the lasing mixture was investigated and it was established that Is displays a tendency to saturate at pressures of 22-23 Torr. It was found that the values of Ps and Is are 3–4 times lower for sealed-off than for continuous-flow operation. The output powers obtained from the resonator in these experiments were ~40% of the ultimate values.
