摘要： The method consists in applying a steady axial magnetic field to the active gaseous medium, in determining either the value of said steady magnetic field which corresponds to the laser-cavity oscillation frequency to be stabilized or the length of the laser cavity corresponding to a set value of the steady magnetic field so that the oscillation frequency should correspond to the peak value of one of the two Doppler curves obtained as a result of the Zeeman effect by splitting the Doppler curve which corresponds to a zero value of the steady magnetic field, in superimposing an alternating axial magnetic field on said steady magnetic field and causing the split Doppler curve to oscillate about a position corresponding to the selected value of the steady magnetic field in order to modulate the output light intensity of said laser, in detecting the modulated output intensity, in comparing the variations in modulation of said output intensity with those of the alternating magnetic field by means of a detector which delivers a signal so that the lightemission frequency of the laser may be corrected by said signal and by a change in length of the laser cavity.
