Abstract: | In this paper, we report on all the electro-optic coefficients of the low-symmetry crystal YbCa4O(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 γ51, γ53, γ42 and γ62 independently. The results obtained are γ11=0.6, γ21=0.4, γ31=0.3, γ13=0.3, γ23=0.2, γ33=2.2, γ51=0.9, γ53=4.1, γ42=0.8 and γ62=0.4×10−12 m/V. |
