DOI: 10.1109/lpt.2021.3078262
Abstract: Featuring extraordinarily curved propagation trajectories, self-accelerating Airy beams have stimulated considerable interests from academic research to practical applications. However, generation of high-quality Airy beams using compact optical devices is still highly desirable. Here we present… read more here.

DOI: 10.1111/jmi.13143
Abstract: Fluorescence nanoscopy methods based on the RESOLFT principle, such as beam‐scanning STED nanoscopy, require the co‐alignment of optical beams for molecular state (on/off) switching and fluorescence excitation. The complexity and stability of the beam alignment… read more here.
