Investigations of the electro-optic behavior of Cs2TeMo3O12 single crystal

摘要

The electro-optic (EO) property of hexagonal Cs2TeMo3O12 (CTM) crystal is studied with interference technique at 632.8 nm. Both the value and sign of the EO coefficients have been obtained and confirmed. The largest EO coefficient is 10.4 pm/V for r33 due to its structure distortion along c-axis. The transverse effective EO effect of r33 and the half-wave voltage are calculated to be 11.08 pm/V and 5200 V at 1064 nm, respectively. The experimental results show that CTM can be one of promising candidates for the EO applications, especially in the mid-infrared region.
