THz wave radiation in periodically poled lithium niobate (PPLN) during optical rectification induced by femtosecond pulse is studied theoretically in this paper. Attention is focused mainly on the distribution of fields in the frequency domain and time domain, and the spectrum width of THz wave radiation. The radiation field pulse duration, the amplitude and the spectrum width varying with the length of crystal and the angle of radiation are also discussed in detail.
