“…The surface nature of this SHG, in combination with strong photorefractivity of BaTiO 3 leads to quite peculiar angular and orientational behavior of the SH light intensity. We believe that our observations performed in a well controlled geometry may clarify a lot of questions concerning still unclear anomalous" SHG in BaTiO 3 reported recently by a number of groups [8,9]. This is especially important for the rapidly developing field of ferroelectric oxide film growth and characterization.…”

“…Further, the authors of [5,6] similarly investigated BiFeO 3 and NaNO 2 single crystals. In addition, we know reports [7][8][9] on the investigation of the SOH generation in single crystal films and ceramics. The question of increasing the efficiency of the SOH localized in a thin subsurface layer of ferroelectrics was also considered in [10,11], where the clusters of barium titanate nanoparticles were investigated.…”

“…(a) SOH spectrum in sodium nitrite microcrystals under exciting radiation power P = 0.252 W and (b) sec ondary radiation spectra(1)(2)(3)(4)(5)(6)(7)(8) in a photonic crystal with sodium nitrite under the excitation with femtosecond pulse periodic laser radiation (λ = 1026 nm) at various pumping powers in a range of 0.06-3.5 W as well as the plasma spectrum (9) under the air breakdown. Arrows denote exciting radiation wavelengths for the second and third optical harmonics.…”
