Abstract

Optical rectification of laser pulses in LiNbO3 by tilted-pulse-front pumping (TPFP) is a powerful way to generate terahertz(THz) pulses. However, comprehensive theoretical analysis is still lack. In this work, we first established and presented a detailed theoretical model for TPFP scheme, which then was used to analyze the pump beam polarization dependent terahertz pulses generated by this scheme. The results indicate that one can change the polarization state of the terahertz pulse by changing the pump beam polarization. A scheme using tilted-pulse-front pumping was also set up, and the generated terahertz pulses have maximal conversion efficiency when the pump beam electric field vector is parallel to the crystal axis, which is consistent with theoretical model.
