Crystals were grown from vapor phase by controlled sublimation in an electric furnace and from alcoholic solution. Crystals were transparent from 2200 \u00c5 with the measurement in the range of ultraviolet and visible spectrum, and showed dodecahedral habit exhibiting a distinct {100} natural growth faces. Crystalline index of refraction at 20\u2103 was measured using microacope to be 1.57 at wavelength of 5893 \u00c5. The electro-optic coefficient \u03b3_\u003c41\u003e was found to be 0.68~1.2x 10- ^\u003c10\u003e cm/V for 5893 \u00c5 at room temperature. The applied voltage required to produce a phase difference of \u03c0, or one-half wavelength is about 63 KV for the crystal grown from alcoholic solution. The wavelength dependence of the electro-optic coefficients, the half-wave voltage, and the conditions for the crystal growth are discussed. Nonlinear susceptibility and the second harmonic coefficnt are estimated to be 0.6 Xl0-^\u003c10\u003e cm/V and the order of l0-^\u003c10\u003e cm/V, respectively.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/23493"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025080X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8\u7d00\u8981. \u7406\u5b66\u7de8"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of Ryukyus.
