“…Moreover, additional excitations by the external laser light may favor the changes of the elasto-optical constants. In the case of relatively weak chemical bonds one can expect an occurrence of substantial optically stimulated piezooptical effects [8]. The nanocrystals embedded into the polymer matrices present a special interest because at the borders between the nanoparticles and the surrounding polymers there occur substantially enhanced dipole moments which determine high sensitivity to the external fields.…”
