Title:
NON-RESONANCE TWO-PHOTON ABSORPTION MATERIAL, OPTICAL RECORDING MEDIUM, OPTICAL RECORDING METHOD AND OPTICAL RECORDING AND REPRODUCING METHOD
Document Type and Number:
Japanese Patent JP2005164817
Kind Code:
A
Abstract:

To provide a non-resonance two-photon absorption material which yields high two-photon absorption efficiency in a wavelength region shorter than a wavelength twice as long as a linear absorption maximum wavelength.

The non-resonance two-photon absorption material contains a compound whose non-resonance two-photon absorption cross-sectional area at one or more wavelengths in a wavelength region shorter than a wavelength given by adding 200 nm to a linear absorption maximum wavelength.
