Pulse-train nonuniformity in an all-fiber ring laser passively mode-locked by nonlinear polarization rotation被引量：4
《Chinese Physics B》2009年第6期2328-2333,共6页罗智超 徐文成 宋创兴 罗爱平 陈伟成 
Project supported by the Natural Science Foundation of Guangdong Province,China (Grant No 04010397)
This paper reports the periodic power variation of the pulse-train in a passively mode-locked soliton fiber ring laser. It can obtain either the uniform or nonuniform pulse-train output by simply rotating the polariza...
