  In spite of the fact that there are different techniques in the creation of
the high-quality liquid crystals (LCs) alignment by means of various surfaces,
the azimuthal and polar anchoring energies as well as the pre-tilt angle are
important parameters to all of them. Here, the modified by a certain manner
aligning layers, previously formed by nonlinear laser lithography (NLL), having
high-quality nano-periodic grooves on Ti surfaces, recently proposed for LC
alignment was studied. The change of the scanning speed of NLL in the process
of nano-structured Ti surfaces and their further modification by means of
ITO-coating, and deposition of polyimide film has enabled different aligning
layers, whose main characteristics, namely azimuthal and polar anchoring
energies, were measured. For the modified aligning layers, the dependencies of
the twist and pre-tilt angles for LC cells filled by nematic E7
({\Delta}{\epsilon} > 0) and MLC-6609 ({\Delta}{\epsilon} < 0) were obtained.
Also the contact angle for droplets of isotropic liquid (glycerol), and nematic
LCs was measured for the various values of the scanning speed during the laser
processing.
