An investigation of stable laser action at room temperature using the F_2 Centers of LiF : Mg crystals is presented. A remarkable reduction in fading of the output signal intensity has been achieved by adjusting the Mg impurity level to an appropriate quantity and by optimizing F_2 Center concentration. It is found that magnesium ions in LiF crystals play a role for suppressing the fading of laser action due to the two-step photoionization process. It is also found that the fading strongly depends on intracavity power and temperature.
