Abstract

We simulated the Cherenkov-phase-matched detection via electro-optic sampling of a lithium niobate (LiNbO3) crystal. The simulation model was curve-fitted with experimental data, achieving a determination coefficient value of R2 =0.9609 for the first oscillation. The validated simulation framework provides a reliable baseline for predicting parameter trends to enhance signal detection in LiNbO3. By parameterizing crystal thickness (d) and probe beam diameter (w0), we identified the key scaling behaviors that maximize the THz signal amplitude.
