Summary:The chaotic fiber laser system comprises a semiconductor pump laser, a wavelength division multiplexer, an erbium-doped fiber, a circulator, the phase shift fiber grating, an adjustable temperature box, an isolator, a first coupler, a second coupler, a long-distance fiber, a photoelectric detector and an oscilloscope. Wherein the phase shift fiber bragg grating is arranged in an adjustable and controllable temperature box, optical signals in an optical path are fed back and injected through a ring by utilizing the narrow linewidth characteristic of the fiber bragg grating, and the optical characteristics of the phase shift fiber bragg grating are controlled by utilizing temperature change, so that the dynamic regulation and control of chaotic laser signals are realized; the invention provides a simple and low-cost dynamic modulation method for the output of the optical fiber chaotic laser signal, and has potential application in the modulation, information uploading and sensing application of the chaotic lase
