 abstract={In present paper, we propose a scheme for generating terahertz (THz) radiation with uniform power distribution by optical rectification of femtosecond laser pulses in periodically polarized lithium niobate (PPLN) crystals. Using a triangular prism-shaped crystal and polarizing the laser along the optical axis, maximum nonlinear coefficient is utilized for efficient THz emission. The periodic domain structure of specific area of the crystal offers quasi-phase matching, which enables cumulative THz radiation with improved uniformity in beam. Moreover, the crystal cutting along the Cherenkov angle allows emitted THz waves to exit with small absorption and reflection losses. The suggested model has a promising method of achieving efficient and uniform THz sources.},
