Abstract
Optical excitation of electronic states of impurities in pyroelectric crystals gives rise to an instantaneous macro-scopic polarization change due to the change of electronic dipole moment. The uses of this effect for fundamental study of ionic and molecular crystals as well as for optical detection, for infrared generation and optical memories are described.Keywords
