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 (TM₀₁) mode is obtained by stretching fiber to adjust phase shift. The laser with TM₀₁ mode has a maximum power of (19.2 ± 0.1) mW and a slope efficiency of (22.02 ± 0.06) %, whose mode purity is approximately (91.8 ± 0.1) %. This method can be extended to generate azimuthally polarized (TE₀₁) or higher order cylinder vector modes. Owing to its compact and high stability, this laser is promising for industrial processing and biomedical applications.

我们提出了一种基于模式叠加原理的全偏振保持光纤（PMF）配置中的圆柱矢量光束（CVBs）激光器生成的新方法。通过使用此方法，可以通过拉伸光纤以调整相移来获得稳定且高纯度的径向偏振（TM ₀₁）模式。具有TM ₀₁模式的激光器的最大功率为（19.2±0.1）mW，斜率效率为（22.02±0.06）％，其模式纯度约为（91.8±0.1）％。可以扩展此方法以生成方位极化（TE ₀₁）或更高阶圆柱矢量模式。由于其紧凑和高稳定性，该激光器有望用于工业加工和生物医学应用。
