Pozycja Kerr constant of Fomblin Z(Wydawnictwo Politechniki Łódzkiej, 2008) Ledzion, Rafał; Karolczak, Stefan; Górski, Piotr; Kucharczyk, WłodzimierzThe Kerr constant B of polyperfluoroethylenemethylene oxide Fomblin Z has been determined within the temperature range 295-323K. At 300K the constant B was found to be equal to 1.7 10(-15) m/V2. The results obtained indicate usefulness of this oligomeric compound as an immersion liquid in measurements of the quadratic electrooptic effect and electrostriction in crystals.Pozycja Effect of temperature on the refractive index and Kerr effect of the transformer oil Nynas Nytro Taurus(Wydawnictwo Politechniki Łódzkiej, 2009) Górski, Piotr; Ledzion, Rafał; Sadowski, Marcin; Kucharczyk, WłodzimierzThe temperature dependence of refractive index of the mineral transformer oil Nynas Nytro Taurus within the range 278-385K is determined. Changes with temperature in the quadratic electrooptic response of the oil are investigated. The results obtained indicate the usefulness of the oil as immersion liquid in measurements of the quadratic electrooptic effect and electrostriction in crystals.Pozycja On the contribution of the quadratic electrooptic effect to the nonlinear response proportional to the fourth power of modulating field(Wydawnictwo Politechniki Łódzkiej, 2007) Izdebski, Marek; Kucharczyk, WłodzimierzIt is shown that the fourth-order electrooptic effect cannot be measured without a background of the contribution that is proportional to the square of the quadratic electrooptic coefficient. The contribution manifests on the fourth power of the modulating field and may be calculated. Thus, if the contribution is found to be comparable with the measured fourth-order electrooptic response, this apparent fourth-order effect should be taken into account in the interpretation ofthe results of the measurement.Pozycja What is the true order of magnitude of the quadratic electrooptic coefficient |g1111-g1122| in RDP crystal?(Wydawnictwo Politechniki Łódzkiej, 2007) Górski, Piotr; Kilański, Łukasz; Ledzion, Rafał; Kucharczyk, WłodzimierzMeasurements based on the dynamic polarimetric technique of the electrooptic coefficient |g1111-g1122| are applied to determine the order of magnitude of the quadratic electrooptic effect in RDP. The results obtained confirm that the effect is two orders of magnitude smaller than widely quoted in the literature data obtained previously by the static polarimetric method.
