Crystals were grown from vapor phase by controlled sublimation in an electric furnace and from alcoholic solution. Crystals were transparent from 2200 Å 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℃ was measured using microacope to be 1.57 at wavelength of 5893 Å. The electro-optic coefficient γ_<41> was found to be 0.68~1.2x 10- ^<10> cm/V for 5893 Å at room temperature. The applied voltage required to produce a phase difference of π, 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-^<10> cm/V and the order of l0-^<10> cm/V, respectively.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理工学部"},{"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":"琉球大学理工学部紀要. 理学編"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of Science & Engineering Division, University of Ryukyus.
