An all-fiber laser generating cylindrical vector beam.
We proposed and demonstrated an all-fiber laser to generate cylindrical vector beam. A pair of fiber-based collimators was used to select the cylindrical vector beam operating. The radially and azimuthally polarized modes can be switchable just by applying pressure to a section of fiber in our fiber laser system. A 70 cm long Yb-doped fiber was used as gain medium and the lasing wavelength was around 1030 nm.
