Quadratic electro-optic effect in KDP-type crystals

摘要

Previous measurements of quadratic electrooptic coefficients in the KDP family of crystals have been analyzed. In addition, the quadratic electrooptic coefficient n$- o$/$+3$/g$-1111$/-n$-e$/$+3$/g$-3311$/ of KDP and ADP has been measured by means of the dynamic polarimetric method. The results obtained confirm that quadratic electrooptic coefficients of KDP-type crystals are of the order of magnitude of 10$+$MIN@20$/ m$+2$/V$+2$/. This is about 100 times smaller than values widely cited in the literature obtained by other authors employing the static polarimetric technique.
