Enhancement of χ(3) of Squarylium Dye J-aggregates in Infrared Region by Two-photon Resonance

Not Accessible

Your library or personal account may give you access

Abstract

Third-order nonlinear optical coefficient (χ(3)) of organic J-aggregate film was measured in infrared region using Z-scan technique. Enhancement of χ(3) due to two-photon resonance was clearly observed, demonstrating the possibility of operation at telecommunication wavelength.
