Oligoetheracrylate polymers as new promising materials for photooperated transparency

The influence of both, the polarized UV-solidifying nitrogen laser pulse duration of 371 nm wavelength and its frequency repetition between 1 and 100 Hz on the anisotropy transparency was studied for a oligoetheracrylate polymer material with two low-power (about 5 mW) continuous semiconducting lasers of 694 nm and 1040 nm wavelengths, respectively. It was revealed substantial angle dependent pump-probe transparency for the red low-power laser beams on the time duration and frequency repetition. Substantial anisotropy of the transmitted polarized laser light with respect to the polarization of the photoinducing laser was found. The effect is a consequence of reorientation of the non-solidified liquid composites which always remain during the UV-solidification. This effect may be used for creation of UV-operating switchers.
