1.5 μm Low Threshold, High Efficiency Random Fiber Laser with Hybrid Erbium–Raman Gain

In this paper, we proposed a novel approach to realize low-threshold, high-efficiency 1.5 <italic>μ</italic>m 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 <italic>μ</italic>m 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 of novel 1.5 <italic>μ</italic>m light sources for diverse applications where stable random lasing output with high-efficiency is essential.
