摘要: A photonic crystal fibre Brillouin laser based on fibre Bragg grating Fabry--Perot cavity is presented. A highly nonlinear photonic crystal fibre 25\,m in length is used as Brillouin gain medium and fibre Bragg grating Fabry--Perot cavity is chosen in order to enhance the laser conversion efficiency and suppress the higher-order Stokes waves. The laser reaches the threshold at input power of 35\,mW, and the experimental laser conversion efficiency achieves 18{\%} of the input power of 140\,mW and does not show higher-order Stokes waves. A photonic crystal fibre Brillouin laser with shorter fibre length and lower threshold is experimentally realized.
