Abstract

The multiple cumulative Rayleigh scattering is the key to the traditional fiber random laser. A doublecavity fiber random laser is fabricated in a capillary tube by a siphon method. Air bubbles are uniformly distributed along the axis of the capillary tube and two incoherent feedbacks to provide optical feedback. The double-cavity fiber random laser emits dual-mode output. The experiment and the theory are in good agreement, promoting the theoretical understanding of mode selection in the weak disordered structure. This work has guiding significance for regulating and optimizing the multi-mode output fiber random laser.

Keywords: Fiber random laser; Double cavities; Dual modes
