Abstract
Variation of principal optical parameters (absorption and refractive indices) in complex oligoetheracrylate photopolymers under influence of nanosecond pulsed nitrogen laser (λ=337nm) at wavelengths of low-power semiconducting lasers (λ=694 nm and 1040 nm) was studied. Two principal mechanisms of the observed changes are discussed: reorientation of the non-solidified liquid composites and topochemical photopolymerization reactions. Besides substantial anisotropy of the transmitted polarized laser light with respect to the polarization of the photoinducing laser beam was found. This effect may be used for creation of UV-operating switchers.
