Abstract
In the paper, we research frequency difference lock of two lasers. In the optical fiber Brillouin sensor, two beams of laser frequency stability around 11G to achieve stimulated Brillouin scattering or heterodyne detection. Currently, we mainly through the optical delay to implement the locking of the frequency difference in the Brillouin sense. through the electric field amplify circuit to improve lock accuracy and improve the system program.
