An erbium-doped fiber laser with a novel cavity--linear multi-cavity is proposed. It is different from a linear single-cavity and a ring-cavity used in fiber laser before. Based on the character of erbium-doped fiber gain at 1550 nm, a laser diode radiated at 980 nm and acted as the pumping source, an erbium-doped fiber employed as gain medium and the linear multi-cavity used as selector, a linear multi-cavity erbium-doped fiber laser radiated at 1558.2 nm is demonstrated with an output power of 10.04dBm and a bandwidth of 0.2 nm under 80 mw power of pump laser. thin addition, the theory of linear multi-cavity erbium-doped fiber laser was discussed in detail.The factors that influences the stability of the output power of fiber laser were analyzed theoretically. Examination results are used for reference to research..
