Description

technical field [0001] The invention relates to a cantilever beam device with increased threshold value of stimulated Brillouin scattering of rare-earth-doped optical fibers, belonging to the fields of high-power narrow-line-width optical fiber lasers and narrow-line-width optical fiber amplifiers. Background technique [0002] Stimulated Brillouin scattering is a nonlinear process that occurs in optical fibers, and the incident power required for it is much lower than that required for stimulated Raman scattering. Once the Brillouin scattering threshold is reached, stimulated Brillouin scattering will convert most of the input power to reverse Stokes waves [Govind P. Agrawal, Nonlinear Fiber Optics, Third Edition, San Diego, CA: Academic]. Obviously, stimulated Brillouin scattering limits the maximum power that the fiber can transmit. In addition, if the stimulated Brillouin scattering cannot be completely suppressed, it will lead to random variation of the pump power, thu...
