主　　题：fiber lasers polarization domains self-mode-locked pulse nonlinear optics 

摘      要：We have observed various polarization domains and a giant self-mode-locked pulse in a 130 m long erbium-doped fiber laser without any mode-locking *** adjusting the intracavity polarization controller,we investigated the evolution process of the polarization domain with the varying cavity *** the birefringence was close to zero,the polarization domains split into multidomains,and finally a giant self-mode-locked pulse formed for the first *** analyzed that the generation of the self-mode-locked pulse was related to the multiple subdomains ascribed to the strong coherent cross coupling between the orthogonal polarization light components in the long fiber cavity.
