Measurement of electro-optic coefficients of low symmetry crystal GdCa4O(BO3)3

In this paper, we report all of the electro-optic coefficients of the low symmetry crystal GdCa4O(BO3)(3) measured by the interferometric method. The new sample orientations, which have not been reported so far, have been used for measuring the skew electro-optic coefficients gamma (51), gamma (53), gamma (42) and gamma (62) independently. The results obtained are gamma (11) = 0.4, gamma (21) = 0.5, gamma (31) = 0.6, gamma (13) = 0.1, gamma (23) = 0.4, gamma (33) = 2.0, gamma (51) = 0.7, gamma (53) = 1.5, gamma (42) = 0.5, gamma (62) = 0.8 x 10(-12)m/V.
