Abstract

The electro-optic (EO), thermo-optic, and dielectric coefficients of pure as well as Nd-doped YCa4O(BO3)3 crystals are determined. The frequency and wavelength dependence of the EO coefficients were determined in the 0–150 MHz and 0.5–1.3 µm ranges, respectively. The analysis of the frequency dependences of both EO and dielectric properties provides the unclamped and clamped values of the whole set of coefficients. It appears that the acoustic contributions to the EO and dielectric properties are very low. Small differences in the properties found for the two crystals are attributed to the Nd doping ions. It is to be noticed that, surprisingly, the birefringence (nX-nY) was found to be independent of the temperature in the range 20–40 °C.

Description of the sample configurations used for the measurements of the EO coefficients ra1, ra2, rc1, rc2, r42, r62, r51, and r53 in the YCOB and Nd:YCOB crystals. X, Y, and Z are the crystallophysical axes. The impinging light beam is linearly polarized at 45° with respect to the neutral lines of the crystal. In the case of the EO coefficients r51 and r53, the gold electrodes were deposited on the X and Z faces; k, beam propagation direction.

(a) Sénarmont arrangement used for the EO measurements. (b) Optical transmission versus the analyser angle β. M0, minimum transmission point for which the output optical signal has a frequency twice as large as the frequency of the applied electric field; M1, 50% transmission point yielding the linear replica of the ac voltage.
