Abstract

The electro-optic coefficients of two crystals have been measured by both static and dynamic methods. For NH₄H₂PO₄, r₆₃=2.54, r₄₁=6.25; for KH₂PO₄, r₆₃=3.15, r₄₁=2.58 (units 10⁻⁷ c.g.s., 20°C λ5560). The variation of the electro-optic response with the frequency of the applied field is given and related to the piezoelectric vibrations of the crystal. A theoretical relation for the difference in the electro-optic constants measured at constant stress and at constant strain is derived, which provides a check on the consistency of the presently available electro-optic, photo-elastic, piezoelectric, and elastic coefficients for these crystals. The use of a.c. methods to obtain high precision in polarization measurements is discussed.
