Complex vector light fields have become a topic of late due to their exotic features, such as their non-homogeneous transverse polarisation distributions and the non-separable coupling between their spatial and polarisation degrees of freedom (DoF). In general, vector beams propagate in free space along straight lines, being the Airy-vector vortex beams the only known exception. Here, we introduce a new family of vector beams that exhibit novel properties that have not been observed before, such as their ability to freely accelerate along parabolic trajectories. In addition, their transverse polarisation distribution only contains polarisation states oriented at exactly the same angle but with different ellipticity. We anticipate that these novel vector beams might not only find applications in fields such as optical manipulation, microscopy or laser material processing but also extend to others.
由于其奇异特性，如非均匀横向偏振分布以及空间和偏振自由度（DoF）之间不可分离的耦合，复矢量光场近来已成为一个热门话题。一般来说，矢量光束在自由空间中沿直线传播，艾里 - 矢量涡旋光束是唯一已知的例外情况。在此，我们引入了一类新的矢量光束，它们展现出以前未曾观察到的新特性，比如能够沿抛物线轨迹自由加速。此外，它们的横向偏振分布仅包含取向完全相同但椭圆率不同的偏振态。我们预计，这些新型矢量光束不仅可能在光学操控、显微镜或激光材料加工等领域找到应用，还可能扩展到其他领域。
