Summary

Organic molecules that absorb two or more photons simultaneously have wide applications in a variety of technologies involving such subjects as optical data storage, 3-D microfabrication techniques, frequency upconverting lasing, optical power limiting, photodynamic therapy, initiators of polymerization reactions, and multi-photon fluorescence microscopy for biological imaging. 

 
Technology Benefit

•    Produces free radicals that initiate polymerization process

•    Three dimensional spatial resolution

•    Absence of single-photon absorption

•    Allows an incident light beam to penetrate deeper into a material

 
Technology Applications

•    Photo-polymerization initiators and two-photon fluorophores 

•    Biological imaging

•    Optical data storage

 

This technology is available for licensing.
