Photoinduced light scattering (PILS) dynamics in LiNbO3:Zn (0.018-0.88 wt.%) and round scattering in LiNbO3:Zn (2.05 wt.%) single crystals excited by a laser radiation Р=110 mW, λо=532.0 nm

Description

Lithium niobate (LiNbO3, LN) single crystals were grown by Czochralski from a congruent melt with addition of ZnO. Crystalline samples were cut as cuboids 7 • 6 • 5 mm3 with edges coinciding with the crystallographic axes X, Y, Z. The samples were irradiated by a laser MLL- 100 on the Y: Al garnet (λ о = 530 nm, P=110mW) perpendicular to the Z axis. Digital camera took a picture of the nonlinear optical process occurring at this every 30 s from the 1 to the 600 s of irradiation. The resulting photoinduced light scattering (PILS) patterns and a round scattering are demonstrated here. The crystals have Zn concentration 0.018, 0.03, 0.52, 0.62, 0.88, 2.05 wt.%.

Steps to reproduce

In order to obtain such results a researcher should grow LN crystal boules with corresponding concentration of Zn, cut samples 7 • 6 • 5 mm3 with edges coinciding with the crystallographic axes, irradiate them with a laser MLL- 100 on the Y: Al garnet (λ о = 530 nm, P=110mW) perpendicular to the Z axis and take digital pictures at every 30 s of irradiation.
