Enhancement of the efficiency of acousto-optic Bragg diffraction due to optical activity. A case of PbGeO crystals
Oksana Mys, Myroslav Kostyrko, Ivan Orykhivskyi +3
We show that the existence of optical activity in an optical material can lead to essential enhancement of acousto-optic (AO) figure of merit for this material. The reason is that…
Acoustooptic operation of optical vortex beams
Iryna Martynyuk-Lototska, Yurii Vasylkiv, Taras Dudok +2
Using acoustooptic (AO) cells based on TeO2 crystal and silica glass, we have experimentally shown for the first time that the intensity profile and the phase structure of the vort…
Torque-operated gradient-index axicon
Yurij Vasylkiv, Mykola Smyk, Ihor Skab +1
We describe a gradient-index axicon based on twisting of crystals. We demonstrate that the focal length of the axicon can be efficiently operated by the torsion moment. The working…
Generation of double-charged optical vortices on the basis of electrooptic Kerr effect
Yurij Vasylkiv, Ihor Skab, Rostyslav Vlokh
We show that double-charged optical vortices can be generated with the help of Kerr electrooptic effect in either single crystals or isotropic media, including gaseous and liquid o…
Spin-to-orbital momentum conversion via electrooptic Pockels effect in crystals
Ihor Skab, Yurij Vasylkiv, Ihor Smaga +1
In the present work we have demonstrated a possibility for real-time operation by orbital an-gular momentum (OAM) of optical beams via Pockels effect in solid crystalline materials…
Optical anisotropy induced by torsion stresses in LiNbO3 crystals: appearance of an optical vortex
Ihor Skab, Yurij Vasylkiv, Viktoriya Savaryn +1
We report the results of studies of torsion effect on the optical birefringence in LiNbO3 crystals. We have found that twisting of those crystals causes a birefringence distributio…
