Da. Akimov et al., OPTIMIZING 2-PHOTON 3-DIMENSIONAL DATA-STORAGE IN PHOTOCHROMIC MATERIALS USING THE PRINCIPLES OF NONLINEAR OPTICS, JPN J A P 1, 36(1B), 1997, pp. 426-428
In the context of designing a three-dimensional optical-memory device,
we investigate the cross section of two-photon absorption of a photoc
hromic material as a function of the relative orientation of polarizat
ion vectors of light waves involved in two-photon data writing. It is
demonstrated that, with an appropriate choice of polarization vectors
of writing laser waves, one can considerably increase the efficiency o
f two-photon data writing.
