Linear electro-optic effect in the organic crystal 4-aminobenzophenone.

The linear electro-optic effect in single crystals of 4-aminobenzphenone (ABP) is reported together with calibration data on LiNbO(3). For ABP the linear electro-optic coefficients r(22) and r(32) at 488 nm were found to be 2.12 and 5.05 pm/V, respectively, with the corresponding reduced half-wave voltages being 49.4 +/- 0.1 and 9.3 +/- 0.1 kV. For LiNbO(3) the half-wave voltage was found to be 4.0 +/- 0.1 kV at 632.8 nm and 2.4 +/- 0.1 kV at 488 nm.
