报道了一种利用双端泵浦的激光二极管(LD)泵浦的微片固体激光器直接产生柱面矢量光束的简单方法。仅通过控制偏振LD离轴泵浦光束的焦位，就可以在普通c切Nd：GdVO4激光腔中产生径向和方位偏振矢量场发射。还观察到了双曲偏振矢量场，打破了矢量场的柱对称性。实验结果通过数值模拟得到了很好的再现。
We report a simple method for generating cylindrical vector beams directly from laser-diode (LD)-pumped microchip solid-state lasers by using dual end-pumping beams. Radially as well as azimuthally polarized vector field emissions have been generated from the common c-cut Nd:GdVO4 laser cavity merely by controlling the focus positions of orthogonally polarized LD off-axis pump beams. Hyperbolically polarized vector fields have also been observed, in which the cylindrical symmetry of vector fields is broken. Experimental results have been well reproduced by numerical simulations.
