The results are compared with the measured pulse shape. Equations describing the chemical kinetics were combined with the gas temperature balance and also a simplified mixing model of oxygen and iodine molecules. A variable magnetic field transforms the CW regime in a pulsed operation. The advantage of the numerical procedure is a possibility to consider an arbitrary temporal dependence of the imposed magnetic field. The method was applied to the experimental data measured on the subsonic version of the COIL device in the Institute of Physics, Prague, where the applied magnetic field had a saw-tooth dependence. After a reasonable agreement of our model for the CW regime with the measured dependence of the laser output, the purpose of this contribution is to confront the magnetically switched regime with the measured pulse shape.
