Abstract: RTP(RbTiOPO4) crystal is a new type electro-optic material which has important application prospects. By spectrophotometer, Nd:YAG mode-locked laser, and withstand voltage tester, its optical and electrical properties are researched systematically, including the transmission spectrum, refractive index, extinction ratio, resistivity, and electro-optic coefficients. The results show that RTP possesses excellent comprehensive properties, like wide transmission range, low absorption loss, high extinction ratio, large resistivity, high electro-optic coefficient and low half-wave voltage. The obtained experimental data will provide a reference for the precise design and optimization of high quality RTP electro-optic devices.
