Abstract

In this paper, the eigenvalue of the super-high precision stable resonator is used as a reference frequency, and the wide-linewidth semiconductor laser is used as a light source. To keep costs down, this work combines the optical feedback effect with the Pound- Drever- Hall laser frequency stabilization method, abandons the electro-optic modulator used in the traditional technology and adopts the optical path tuning method to carry out the phase modulation of the incident light field. The document derives from the shape of error signal in frequency stabilization technology in the presence of optical feedback effect notionally. As per this error signal, the length of resonator cavity is controlled by feedback controlled via the circuit system, and then successfully stabilizes the resonant frequency of the resonator at the center frequency of the laser output.
