Abstract

Highlights: A mode-selective coupler at 1.0 μm wavelength band has been proposed and fabricated. Cylindrical vector beam generation from Ytterbium-doped fiber laser. Cylindrical vector beam laser operating on dissipative soliton resonance. Both radially and azimuthally polarized beams have been obtained. Abstract: We experimentally demonstrate a dissipative soliton resonance (DSR) Ytterbium-doped fiber laser with high-purity cylindrical vector beam (CVB) generation, using a mode-selective coupler (MSC) as transverse mode converter and splitter. The all-normal-dispersion mode-locked Ytterbium-doped fiber laser operating at DSR regime without spectral filter can deliver CVB pulses with a pulse duration of ∼733 ps and a pulse energy as high as ∼0.439 nJ. The radially and azimuthally polarized beams can be switched by adjusting the polarization controller, with a high mode purity measured to be >94.5%. This compact DSR fiber laser could find potential applications in the field of material processing, nonlinear optics and so on.
