Two-Photon Absorbing Molecules Hint at New Applications

Facebook Twitter LinkedIn Email
TUCSON, Ariz., March 16 -- Two University of Arizona scientists who developed molecules that simultaneously absorb two photons of light now report that the molecules' sensitivity to laser beams suggests a number of potential photonics applications. In a Nature magazine article Joseph W. Perry and Seth R. Marder of the University's chemistry department report that two-photon-absorbing polymers, or resins, can be produced and used for three-dimensional optical data storage and for three-dimensional manufacturing of microscopic parts for subminiature optical or mechanical devices. The scientists assert that lasers practical for industry provide sufficient power to excite the new two-photon absorbing molecules.
