Abstract
The photoinduced grating for polymer embedded micropowders of Bi1−x Eu x FeO3 (BEFO) with \( {\text{x}} = 0, \, 0.05, \, 0.10{\text{ and }}0.20 \) synthesized by sol–gel method were studied. The illumination by the laser has lead to occurrence of micro-grating with period varying from 50 up to several hundred micrometers. The maximal grating frequency was observed for the treatment by lasers at wavelength 1540 nm formed by Er:glass 12 ns lasers. The incident polarized laser light was split on two and was incident on the samples under the angle up to 40°. Optimal parameters were obtained for the samples with x = 0.15. The possible mechanisms of the observed micro-gratings are discussed.
