| 摘 要： | A photonic crystal fibre Brillouin laser based on fibre Bragg grating Fabr-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.

| Abstract: | A photonic crystal fibre Brillouin laser based on fibre Bragggrating Fabry--Perot cavity is presented. A highly nonlinearphotonic crystal fibre 25,m in length is used as Brillouin gainmedium and fibre Bragg grating Fabry--Perot cavity is chosen inorder to enhance the laser conversion efficiency and suppress thehigher-order Stokes waves. The laser reaches the threshold at inputpower of 35,mW, and the experimental laser conversion efficiencyachieves 18{%} of the input power of 140,mW and does not showhigher-order Stokes waves. A photonic crystal fibre Brillouin laserwith shorter fibre length and lower threshold is experimentallyrealized. |
