Three-photon Absorption Process In Organic Dyes Enhanced By Surface Plasmon Resonance
Multi-photon absorption processes have received significant attention from the scientific community during the last decade, mainly because of their potential applications in optical limiting, data storage and biomedical fields. Perhaps, one of the most investigated processes studied so far has been …

MULTIPHOTON ABSORPTION IN MONOLAYER TRANSITION METAL DICHALCOGENIDES
Identifying light absorption mechanisms in nanoscale materials, which are more efficient than those observed in bulk semiconductors, are of paramount importance to next-generation, infrared photo-detection. In this thesis, degenerate two-photon absorption (2PA) and three-photon absorption (3PA) …

Optical resistance of dielectric coatings to multi-pulse femtosecond laser radiation /
… observed at the wavelength where two-photon absorption changes to three-photon absorption. This confirms that multiphoton absorption is one of the main damage mechanisms in femtosecond range. The multilayer coatings deposited by IAD and e-beam techniques on substrates having roughness …

Nonlinear Optical Response of Simple Molecules and Two-Photon Semiconductor Lasers
… of simple molecules, and the potential of a two-photon laser using a bulk semiconductor gain medium. Within the Born-Oppenheimer approximation, nonlinear refraction in molecular liquids and gases can arise from both bound-electronic and nuclear origins. Knowledge of the magnitudes, temporal …
