摘　　要：We present a laser frequency locking system based on acousto-optic modulation transfer spectroscopy（AOMTS）. Theoretical and experimental investigations are carried out to optimize the locking performance mainly from the view of the modulation frequency and index for the specific scheme of AOMTS. An FWHM linewidth of 63 kHz is achieved and the frequency stability in terms of Allan standard deviation reaches1.4 × 10^（-12） at 30 s. The frequency shifting capacity is validated throughout the acousto-optic modulator bandwidth while the laser is kept locked. This work offers a different but efficient choice for applications calling for both stabilized and tunable laser frequencies.We present a laser frequency locking system based on acousto-optic modulation transfer spectroscopy（AOMTS）.
