Journal ArticleDOI
Nonlinear absorption study of a C 60 -toluene solution
Daniel G. McLean,Richard L. Sutherland,Mark C. Brant,Donna M. Brandelik,Paul A. Fleitz,T. Pottenger +5 more
TL;DR: A five-level model of C60 yields excellent agreement with both pulse-width data sets for incident fluences as high as approximately 1 J/cm2 and additional phenomena observed at higher fluences indicate that other mechanisms may be active and contribute to optical limiting in this regime.
Journal ArticleDOI
Switchable Holographic Polymer-Dispersed Liquid Crystal Reflection Gratings Based on Thiol−Ene Photopolymerization
Lalgudi V. Natarajan,Christina K. Shepherd,Donna M. Brandelik,Richard L. Sutherland,Suresh Chandra,Vincent P. Tondiglia,D. W. Tomlin,Timothy J. Bunning +7 more
TL;DR: In this paper, an electrically switchable reflection gratings in blue, green, yellow, and red colors were fabricated by photopolymerization of polymer-dispersed liquid crystals.
Journal ArticleDOI
Electro-optical switching characteristics of volume holograms in polymer dispersed liquid crystals
TL;DR: In this paper, a photopolymer-liquid crystal composite material system for writing in a fast single step, high diffraction efficiency volume holograms, capable of switching in applied electric fields of low voltage.
Patent
Switchable polymer-dispersed liquid crystal optical elements
TL;DR: Holographic polymer-dispersed liquid crystal (H-PDLC) as mentioned in this paper is a switchable photopolymer that can be switched on and off with the application of an electric field.
Journal ArticleDOI
Excited-state characterization and effective three-photon absorption model of two-photon-induced excited-state absorption in organic push-pull charge-transfer chromophores
Richard L. Sutherland,Mark C. Brant,Jim Heinrichs,Joy E. Rogers,Jonathan E. Slagle,Daniel G. McLean,Paul A. Fleitz +6 more
TL;DR: In this article, the authors investigated two-photon and excited-state absorption in D-pi-A chromophores and proposed a model to explain nonlinear absorption in the nanosecond regime.
