Applying a bicolor coherent treatment of a Nd-YAG laser with wavelength 1.32 μm and its second harmonic generation, we have investigated photoinduced SHG in Au nanoparticledeposited ZnO nanocrystallinne (NC) films. We have established that coexistence of the such crystallites gives substantially better results compared to the pure ZnO NC deposited onto the glass substrate. It was shown that the value of the second order susceptibility obtained for the large incident angles of the fundamental and writing beams is equal to about 23 pm/V. The better results are obtained during the phototreatment at temperatures near the 60 oC for the Au doped samples and is almost non-sensitive to temperature for the pure samples. The further increase of the temperature leads to decay of the optical second harmonic generation

We present a new technological approach of using the known piezooptical glasses for telecommunications by introduction of the silver nanoparticles. The main principle consists of existence of the surface plasmon resonances of the silver nanoparticles in the spectral range 480 nm - 530 nm. The latter one favors an increase of their elastooptical properties closely connected with the acoustooptical efficiencies. Principal parameters of the silver nanoparticles, e.g. their concentration, nanoparticle sizes and type of the glasses is discussed.

A method of formation of oligoetheracrylate photo-solidified fibers is proposed. The solidification process is performed by UV-nanosecond 337 nm nitrogen laser. Using different profiles of the light masque the optical fibers with the operated birefringence are formed with averaged diameter about 80- 100 mum. Two principal mechanisms of the observed changes are discussed: reorientation of the non-solidified liquid oligoetheracrylate composites and topochemical photo-polymerization reactions. Substantial anisotropy of the transmitted polarized light at 694 nm and 1040 nm with respect of the UV-solidified beam is obtained.
