Experimental setup for EO measurements. 1: He–Ne laser, 2: polarizer, 3 and 6: holophote, 4: beam splitter, 5: sample, 7: ADP crystal, 8 and 9: high-voltage amplifier, 10: low-frequency signal generator, 11: convex lens, 12: diaphragm, 13: photodetector, and 14: lock-in amplifier.
Orientations of the samples in EO coordinate system.
The sample orientations and relative piezoelectric coefficients. , , and are the axis in the piezoelectric coordinate that have once or twice rotations, are the piezoelectric coefficients which have been rotated around axis by an angle , and are the piezoelectric coefficients which have another rotation around based on the first rotation.
EO coefficients of crystal at room temperature.
