    High-Speed Fluorescence Imaging and Intensity Profiling of Femtosecond-Induced Calcium Transients by Daniel Day, Charles G. Cranfield, Min Gu

    Published 2006-01-01
    “…As a result of the stimulation, calcium waves can be generated in COS cells, and laser-induced calcium oscillations are initiated in the GH3 cells. Single-photon fluorescence images and intensity profiles of the targeted specimens are sampled in real-time using a modified PerkinElmer UltraView LCI microscope.…”

    High-order optical Hall effect at the tight focus of laser radiation by V.V. Kotlyar, S.S. Stafeev, E.S. Kozlova

    Published 2023-10-01
    “…It is shown that when focusing a linearly polarized optical vortex with unit topological charge, four local subwavelength regions are formed in the focal plane, in which directions of the longitudinal projection of the spin angular momentum are opposite in the neighboring regions. That is, photons falling into neighboring regions in the focus have the opposite spin. …”
