摘要
用干涉法和准静态ｄ_（３３）测量仪相结合测量了β－ＢａＢ_２Ｏ_４（β－ＢＢＯ）晶体的全部压电应变系数，结果为：ｄ_（３３）＝１．０×１０^（１２）Ｃ／Ｎ，ｄ_（３１）＝－０．８３×１０^（１２）Ｃ／Ｎ，ｄ_（２２）＝２．２×１０^（１２）Ｃ／Ｎ，ｄ_（１５）＝２１．２×１０^（１２）Ｃ／Ｎ。
In this paper,all of the piezoelectric strain eonstants of β-BaB2O4 (β-BBO) singlecrystal are measured by interferometric method in conjunction with a quasi-static d33 measurer. Theresultants obtained are d33=1.0 ×10-12 C/N,d31=-0. 83 ×10-12 C/N,d22=2. 2 ×10-12 C/N,d15=21.2×10-12 C/N.
