Webb19 dec. 2016 · Similarly the focal spot corresponding to w 0 = 0.125 is around 1.74 λ which then confined around 0.56 λ, 0.478 λ and 0.42 λ corresponding to w 0 = 0.250, 0.375, and 0.500 respectively. Hence it is observed that increasing both the beam order and waist size decreases the focal spot as well as the focal depth of the focal structure.

WebbCylindrical vector beam (CVB) has been verified to enable resolution improvement in tip-scanning imaging, nonlinear imaging, stimulated emission depletion (STED) microscopy, … WebbThe focused spot before the interface has a very small spot with size of 0.48λ. However, the spot size is enlarged up to 0.93λ in the glass. This abrupt increment in spot size from air to glass makes the RP beam poor in achieving a small spot. This is mainly due to the abrupt decrease of longitudinal field in glass for the i m obsessed with you
