论文摘要
我们证明了所有极化维护纤维（PMF）激光器，可以提供选择性的横向模式发射。 PMF部分之间的偏移和交叉剪接用于生成更高的订单模式并产生双折射诱导的模式过滤器。极化旋转技术（PRT）用于选择输出光束轮廓。探索了线性腔和环腔。在实验上，分别从所有PMF线性腔激光器和一个环腔激光器中实现了360°旋转的LP11模式和带有加和负1拓扑的OAM涡流束。
We demonstrated an all polarization-maintaining fiber (PMF) laser which could offer selective transverse mode emission. Offset and cross splicing between PMF sections was used to generate higher order mode and to yield a birefringence induced mode filter. Polarization rotation technique (PRT) was used to select the output beam profile. Both linear cavity and ring cavity were explored. Experimentally, 360° rotating LP11 mode and OAM vortex beam with plus and minus 1 topological charges have been realized from an all PMF linear cavity laser and a ring cavity laser respectively.
