title: Terahertz generation based on difference frequency generation by rotating fan-out poled LiNbO3.
abstract: Theoretical analysis of terahertz (THz) generation based on difference frequency generation (DFG) by rotating fan-out poled LiNbO3is presented. The uncertainty of poling vectors during clockwise and counterclockwise rotation of the fan-out poled LiNbO3at the center of the crystal input face is investigated. The poling period along the propagation direction of the input pump and signal waves during clockwise and counterclockwise rotation is calculated. The dependence of THz vectors on rotation angles is numerically simulated. The relative intensities of a THz wave during clockwise rotation of the fan-out poled LiNbO3are calculated.
