Abstract

The electro-optic performance in free space at the 2 μo wavelength range of potassium lithium tantalate niobate (KLTN) crystal operated at the paraelectric phase close to the phase transition temperature (Tc) is explored. An electrically induced change in the refractive index approaching 0.01 was demonstrated close to the phase transition temperature, while maintaining high optical quality and transparency at a wavelength of 1.85 μo A special crystal geometry was employed in order to suppress unwanted acousto-optic oscillations that were superimposed on the generated pulse due the strong electrostriction of KLTN close to Tc.
