Abstract:In this paper, we proposed a novel approach to realize low-threshold, high-efficiency 1.5 μm random fiber laser by taking advantage of hybrid Erbium–Raman gain. The numerical model is established to optimize the proposed Erbium–Raman random fiber laser, revealing the route to generate high-efficiency random lasing. The experiment is conducted to verify the concept, in which the threshold of 1.55 μm random lasing has been reduced to 75 mW and its optical conversion efficiency has reached record high (65.5%). This simple and efficient random fiber laser could provide a platform for development..
