Optical retification of laser pulses in LiNbO₃ by tilted-pulse-front pumping(TPFP) is a powerful way to generate terahertz(THz) pulses. Detailed theoretical analysis of the TPFP THz pulses generation efficiency and polarization with different pump beam polarization was presented. The THz generation efficiency for various of pump beam polarization angle and THz pulse polarization were also researched. The results predict that the magnitude of the THz electric field is maximized when the pump beam electric field vector is parallel to the LiNbO₃ crystal axis. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
