Abstract: Abstract The saturated and two-photon absorption of various classes of heterocyclic dyes [thiazine (thionine), xanthene (erythrosine), and carbocyanine (3,3′-di-(γ-sulfopropyl)-4,4′,5,5′-dibenzo-9-ethylthiacarbocyaninebetaine pyridinium salt, DEC)] possessing optical absorption in the 500–680 nm range were measured at the wavelengths of… read more here.

Abstract: We improved the three-dimensional spatial resolution of laser scanning transmission microscopy by exploiting the saturated absorption of dye molecules. The saturated absorption is induced by the high-intensity light irradiation and localizes the signal within the… read more here.

DOI: 10.1364/prj.6.0000c8
Abstract: Here, we used the micro P-scan method to investigate the saturated absorption (SA) of different layered Bi2Se3 continuous films. Through resonance excitation, first, we studied the influence of the second surface state (SS) on SA.… read more here.
