WebJun 20, 2024 · Abstract. We presented a method to construct an all-fiber laser by using an acoustically-induced fiber grating (AIFG) in two-mode fiber (TMF) within the laser cavity to generate cylindrical vector beams (CVBs) in communication band. Based on the polarization dependent vector mode coupling characteristic of an AIFG, the CVBs were … WebNov 5, 2024 · There are three types of fiber modes.

WebJul 1, 2024 · We propose a novel method for the generation of a cylindrical vector beams (CVBs) laser in an all-polarization-maintaining fiber (PMF) configuration based on the principle of mode superposition. By using this method, a stable and high purity radially polarized (TM 01) mode is obtained by stretching fiber to adjust phase shift.
