ing at the differences in sweep speed, step size, range, accuracy, and signal-to-noise ratio (SNR) of linear sweep lasers, this study proposes a scheme for directly generating an acousto-optic modulation-based frequency-scanning laser. It adopts a ring-shaped cavity structure, which has the characteristics of fast sweeping speed, high frequency sweeping precision, and high SNR. The existing frequency-scanning laser is optimized by analyzing the effects of the laser's SNR and length of the erbium-doped fiber in the erbium-doped fiber amplifier on the performance of the generated frequency-scanning laser.
