In this paper we investigate the polarization properties of a fiber laser with an intracavity c-cut calcite crystal that is capable of producing reconfigurable vectorial output modes. Vectorial modes with radial, azimuthal and generalized cylindrical vector polarizations can be generated by translating one lens within the laser cavity. Detailed studies of the mode polarization evolution show that the modes inside the laser cavity can be spatially homogeneously polarized in one section of the cavity while being spatially inhomogeneously polarized in another section of the cavity, which opens the opportunities for many potential new fiber laser design possibilities and applications. Furthermore, more complicated vectorial vortex output modes are also observed by purposefully introducing angular misalignments.
在本文中，我们研究了一种腔内含有c切割方解石晶体的光纤激光器的偏振特性，该激光器能够产生可重构的矢量输出模式。通过在激光腔内平移一个透镜，可以产生具有径向、方位角和广义圆柱矢量偏振的矢量模式。对模式偏振演化的详细研究表明，激光腔内的模式在腔的某一段可以在空间上均匀偏振，而在腔的另一段则在空间上非均匀偏振，这为许多潜在的新型光纤激光器设计可能性和应用开辟了道路。此外，通过有意引入角度失准，还观察到了更复杂的矢量涡旋输出模式。
