The fiber laser, an innovative laser type, holds immense significance in optical communication, industrial processing, and scientific research owing to its remarkable high power and efficiency combination. The 1550nm light wave, widely utilized in fiber communication, renders the research and production of fiber lasers in this range pivotal for diverse applications. Within the pages of this paper, we delve into the intricate design and meticulous investigation of an erbium-doped fiber laser operating within the 1550nm-1600nm band. Our noteworthy achievement lies in the adept attainment of laser emission at 1575 nm. This success is intricately woven into the reciprocal reflection of pump light within the resonant cavity of the fiber laser and the nuanced electronic transition process of erbium ions. This paper not only unfolds a detailed exploration of the structural nuances but also unveils the design principles, methodology, and results of MATLAB simulations employed in crafting erbium-doped fiber lasers. Exhibiting exemplary performance at the 1550nm wavelength, this laser proves promising in realms such as optical communication and medical applications, signalling a paradigm shift in the possibilities within these domains. The research presented herein introduces avant-garde concepts for designing high-performance fiber lasers, providing a rich foundation for further exploration in related fields. Through this comprehensive discourse, we aim to contribute not only to the advancement of fiber laser technology but also to the expansion of possibilities in optical communication and beyond.

In this paper, a new chaotic system is proposed by adding a magnetron memristor to an erbium-doped fiber laser circuit, and its dynamical characteristics are analyzed. A special periodic coexistence attractor phenomenon was discovered during the analysis, which affects the dynamical characteristics of the system by changing the time parameters of the AC power supply and it is controllable. Finally, the chaotic system is implemented by constructing an equivalent analog circuit. Theoretical analysis and simulation results show that the new erbium-doped fiber laser chaotic system has good dynamical characteristics and it is easy to implement. Meanwhile, the rich dynamical characteristics of the system provide a basis for its application in image encryption and other fields.
