Abstract

We investigated terahertz pulses from a rotating fan-out type poled lithium niobate (LiNbO₃) pumped by femtosecond laser pulses. In particular, the rotating fan-out type poled sample produces an uncertain phase-matching wave vector perpendicular to input laser pulses. Such a wave vector allowed us to observe terahertz pulses normally unobservable from bulk or periodically poled LiNbO₃ at large rotation angles because of the terahertz wave critical angle of LiNbO₃. Further, we explained center frequency dependence on rotation angles by difference frequency generation process with the uncertain wave vector. We also discussed bandwidth dependence and terahertz pulse power regarding rotation angles.
