On the nature of temperature dependance of intrinsic quadratic electrooptic coefficients in KDP-type crystals

Kucharczyk W., Ledzion R., Górski P., Izdebski M.

Scientific Bulletin. Physics / Lodz University of Technology

2010

Vol. 31

37-42

It is shown that the fourth-order electrooptic effect may be responsible for the temperature dependence of the quadratic electrooptic coefficients defined in terms of polarization. An example is given for the ammonium dihydrogen phosphate (ADP) crystal.

Pokazano, że efekt elektrooptyczny czwartego rzędu może być odpowiedzialny za zmiany temperaturowe współczynników właściwego kwadratowego efektu elektrooptycznego. Rozważono przypadek kryształu ADP.

Measurement conditions of the quadratic electrooptic coefficients along the optic axis in uniaxial crystals

Izdebski M., Kucharczyk W.

Optica Applicata

2003

Vol. 33, nr 1

213-218

Following our previous discussions of measurement accuracy of electrooptic coefficients in uniaxial crystals the light wave propagation along the optic axis of ammonium dihydrogen phosphate (ADP) in a field that bisects the X and Y crystallographic axes is considered. We analyse the effect of imperfection in crystal cutting and alignment by means of computer analysis based on the Jones calculus. It is confirmed that, for relatively small inaccuracies, the values of the quadratic electrooptic coefficients can be significantly larger when measured with a static field than those measured with a sinusoidal one.
