Abstract

Abstract : Fiber lasers based on random distributed feedback have attracted increasing attention in recent years. In this review article, recent advances in high‐power random distributed feedback fiber lasers (RDFFL) is provided, including the theoretical analyses, experimental approaches, discussion on the practical applications and outlook. It is believed that high‐power RDFFL could become a promising light source with simple and economic configurations. Abstract : A fiber laser based on random distributed feedback has attracted increasing attention in recent years, as it has become an important photonic device and has found wide applications in fiber communications or sensing. In this article, recent advances in high‐power random distributed feedback fiber laser are reviewed, including the theoretical analyses, experimental approaches, discussion on the practical applications and outlook. It is found that a random distributed feedback fiber laser can not only act as an information photonics device, but also has the feasibility for high‐efficiency/high‐power generation, which makes it competitive with conventional high‐power laser sources. In addition, high‐power random distributed feedback fiber laser has been successfully applied for midinfrared lasing, frequency doubling to the visible and high‐quality imaging. It is believed that the high‐power random distributed feedback fiber laser could become a promising light source with simple and economic configurations.
