WebFeb 1, 2024 · Nonlinear harmonic generation in metasurfaces has shown great promise for applications such as novel light sources, nonlinear holography, and nonlinear imaging. In particular, dielectric metasurfaces have shown multifold enhancement of the harmonic efficiency in comparison to their plasmonic counterparts due to lower optical loss and … WebNov 1, 1995 · Optical third-harmonic generation (THG) is generally a weak process but is dipole allowed, therefore it occurs in all materials, including dielectric materials with inversion symmetry. We report that when using focused high-intensity ultrashort laser pulses, this normally weak THG process becomes highly operative at a simple air … WebMaterials with multiple nonlinear-optical responses have been investigated widely in recent years. Here, we report a hybrid system with both giant multiphoton absorption (MPA) and efficient third harmonic generation (THG) excited by near-infrared femtosecond laser pulses. The hybrid material consists of both biomin sensitive toothpaste
