Optical poling of oligoether acrylate photopolymers doped by stilbene-benzoate derivative chromophores

Abstract

On p 238, the last sentence of the second paragraph `From our experiment we have estimated the value of the electric field, which corresponds to the value χ(2), to be ~102 - 104 V cm-1.' should be replaced by the following more precise and detailed sentence.`From our experiment on electric-field poling we have found that to achieve the same nonlinear optical susceptibility as during the optical poling, it is necessary to apply an external aligning (not effective dc-internal, which will be different) electric field of 102 - 104 V cm-1, depending on the degree of photosolidification.'
