The model includes a fairly complete chemici kintetics. The variable magnetic field transforms the CW regime in a pulsed operation. The numerical procedure gives a possibility to tackle an arbitrary temporal dependence of the imposed magnetic field and to calculate directly the response of the laser output. The calculation was focused on the data measured with the subsonic version of the COIL device in the Institute of Physics, Prague, modulated by a saw-tooth magnetic pulses. Although the model gives a reasonable agreement for the CW regime it is difficult to match the exact shape of the measured magnetically switched laser pulses with the calculated one. In this contribution we shall demonstrate various additional refinements of the model to improve the agreement with the measured pulse shape.
