In birefringent fiber lasers, a new type of optical solitons involving two orthogonal polarization components were found, which are termed as vector solitons [1]. Due to the potential applications in pulse shaping and microwave photonics, many optical methods were proposed to synthesize Gaussian monocycle pulses (GMPs) and Gaussian doublet pulses (GDPs), which have the shapes of the first and second derivatives of Gaussian functions respectively [2]. In this paper, we demonstrate that GMPs and GDPs can be generated in a ring-cavity erbium-doped fiber laser (EDFL) with polarization-locked vector solitons. We further employ qualitative analysis for the interactions of system parameters and their combined effects on the pulse shaping, by solving the coupled complex Ginzburg-Landau equations (CGLEs) with sech- and tanh-based functions.
