I develop the theory of molecular orientation induced by two-photon isomerization.
Phenomenologically, two-photon isomeric orientational hole burning and reorientation …

The photo-induced birefringence of three new azo polymer films containing different
substitutions was studied. Under a pumping light with the same polarization and intensity …

Near-resonant optical pumping was used to modulate third-order susceptibility χ (3) in
disperse red 1 doped poly (methylmethacrylate) thin films. An optically pumped degenerate …

Azo copolymers are nonlinear-optical materials, in which polar orientation can be induced
by optical poling or electrical poling. We report a new efficient approach to performing photo …

Polar orientation created by local photo-assisted poling (PAP) in copolymer films containing
disperse red 1 was investigated by scanning probe microscopy. PAP was performed by a …

Near-resonant optical pumping is used to encode an anisotropy of third-order susceptibility χ
(3) in azo-dye doped polymethylmethacrylate thin films. The χ (3)-anisotropy is probed with …

Substantial anisotropy of photoinduced change of third harmonic generation (THG) was
observed during investigation of the 3-(4-nitrophenyl)-6-N, N-diphenylamin-1-phenyl-1H …

Recovery speed of photoinduced third-harmonic (TH) generation in azo-copolymer thin films
can be controlled by a nanosecond laser excitation. When the excitation is tuned on, the TH …

The low, third-order nonlinear optical characteristics, as compared with the poly (3-
hexylthiophene)[RRP3HT] thin film made on the fused silica substrate by the drop casting …

The third-order nonlinear optical properties of regioregular poly (3-hexylthiophene)(RR-
P3HT) thin films prepared on fused glass substrate were evaluated. The surface modification …
