We compared the detected THz power through electro-optic detection for different spot sizes of a probe beam on the < 110 > ZnTe crystal. We find that there is a proportional relationship between the detected THz power and spot size of the probe beam by theoretically analyzing its effect on the intensity profile of the terahertz beam.
