| Abstract: | We have characterized the wavelength dispersion of the high- and low-frequency values of the linear electro-optic coefficient r
c = r
33–(n
o/n

r
13 of poled 0.88 Pb(Zn1/3Nb2/3)O3–0.12 PbTiO3 single crystal. The measurements have been investigated as a function of the laser wavelength from 0.465 to 1.32  m. Clamped r
S and unclamped r
T values of the electro-optic coefficient as well as the acoustic contribution r
a have been established. We obtained a ratio of r
S/r
T = 30%, which is independent of the wavelength of the light beam. The value of r
S
c at the wavelength of 633 nm was found to be equal to 50±5 pm/V, which is a rather high value.This revised version was published online in March 2005. In the previous version, the published online date was missing |
