Abstract
Third‐order nonlinear optical susceptibilities (χ(3)) were estimated by third‐harmonic generation for some electroconductive oxide thin films with wide band gaps (∼3.5 eV). Tin dioxide (SnO2) films showed the highest χ(3) as 3.8×10−12 esu, which is comparable with that of polydiacethylene (PDA) casting films that possess conjugated π electron systems.Keywords
