Abstract


Erbium-doped fiber laser has been widely used as a novel laser source and optical amplifier , to become the research focus due to the chaotic unpredictability of the impact on the stability of the optical system , the laser chaotic control study . This paper presents a bicyclic single-mode erbium-doped fiber laser coupled feedback phase shift control method , according to the the coupling feedback phase shift control method of the control principle established control model ; kinetic equation derivation based on the method of control , and simulation to prove the feasibility of the control method ; further analysis , the summary of the control law for the control method and system output for the state single-cycle variation of the oscillation period . The specific content of the research include: First, the establishment of a bicyclic erbium-doped fiber laser kinetic equation . Combined generation principle of the laser , erbium-doped fiber characteristics and laser resonator works theory , consider the bicyclic structure doped erbium fiber laser bicyclic erbium-doped fiber laser kinetic equation ; theoretically zero steady state solution linear stability analysis to determine bicyclic doped the bait fiber laser threshold conditions . Second, analysis of bicyclic erbium-doped fiber laser dynamics and chaos control method . Discuss the variation of the output of the system under different conditions , and has several comparative analysis control principle of chaos control method and chaos control effect . Finally, the proposed bicyclic singlemode erbium-doped fiber laser laser chaos coupled feedback phase shift control method . Control model to establish the control methods , from a theoretical analysis of the role of the control of the control parameters in the control model ; simulation analysis to discuss the parameters of the two control systems control , summarizes the changes in the two control parameters of the control law of the state of the system output ; and further discuss the system chaotic control to the state single-cycle variation of the oscillation period . The proposed bicyclic singlemode erbium-doped fiber lasers laser chaos coupled feedback phase shift control method , bicyclo single-mode erbium-doped fiber lasers dual - parameter control , and to expand the scope of the control ; complete analysis of the control law of the control method for chaotic the control law has certain reference value ideas and methods .
