Compared with the frequency stabilization based on saturated absorption,a Doppler-free dichroic lock system is not sensitive to the noise of light intensity and it is hard to lose the lock.Its light path is simple and feasible.The output frequency of this method has no modulation disturbance,but it still needs a specific absorption line to match the frequency.Therefore,its application is also very limited.Though its stability is higher than DAVLL,it is more sensitive to the intensity of magnetic field,because the slope of the difference signal is greatly influenced by the intensity of the magnetic field[29].
