Crossed-beam two-photon readout system for three-dimensional radiation dosimeters

Journal Article (Journal Article)

A two-photon readout system, that allowed for the readout of information on ionizing radiation from the three dimensional (3D) optical random access memory (ORAM) materials without polymer fracturing, was investigated. A Q-switched, frequency-doubled Nd:YAG laser was used as the two-photon excitation source. An optical attenuator was employed to adjust the intensity of the 1064 nm laser beam. It was found that the two-photon excited fluorescence of anthracene-doped 3D ORAM materials could be obtained without polymer fracturing.
