Abstract The generation of THz pulses from stoichiometric LiNbO3 (sLN) crystal with tilted-pulse-front excitation is studied. In this scheme, THz absorption by sLN is obtained by numerical interpolation based on the measured data. It shows that THz generation can be enhanced by decreasing the temperature of sLN. The refractive indices of the laser from visible to mid-infrared regime are calculated from the Sellmeier dispersion equation. Then the THz generation law pumped by visible and mid-infrared laser pulses is calculated. It is found that the THz amplitude and energy increase in the near-infrared regime and then tread to a constant value when the wavelength of the laser pulses increases.
