| Abstract: | RbTiOAsO4(RTA) single crystals of optical quality up to dimension 20 mm36 mm52 mm were grown by the flux method. Determination of the distribution of piezoelectric constants and the etched surface topographies prove that the grown crystals are in a single domain condition. Its wide transparency range, good frequency doubling properties, lower conductivity and lower dielectric loss are reported in the paper together with its ferroelectric transition and dielectric constants and piezoelectric constant. It is not only a potential nonlinear optical crystal used in SHG and infrared optical parametric oscillator, optical parametric amplifier, but also an excellent optical and electro_optical crystal. |
