Abstract: The high conversion generation efficiency THz generation through optical rectification using a tilted optical pulse front is described. A calculation method of tilted-pulse-front scheme has detailed descriptions, including the tilt introduced by the grating, increase of the pulse front tilt by demagnification in the imaging of the pulse from the grating onto the generation crystal, and propagation of the tilted intensity front from free-space into the generation crystal. We get an optimal demagnification 3.75 of the imaging system for maximum THz conversion efficiency (＆0.1519×10-3)
Keywords: Terahertz , Lithium niobate (LiNbO3 ), Optical rectification, Tilted pulse fronts.
