Abstract A detailed study of the gain dynamics of the pulsed, optically pumped 4.3 μm CO2 laser is described. Small-signal gain coefficients as high as 14%/cm are measured in a 4.3 μm amplifier using low-power pulses from a 4.3 μm probe laser. The measurements are compared with a rate-equation model and good quantitative agreement is obtained. The model, which uses no adjustable parameters, is described in detail. Gain is studied as a function of optical pumping power, gas mixture, gas pressure and discharge excitation of the 4.3 μm amplifier. Optimization of the gain is discussed.
