In this study, we investigated generation of THz waves via the d133 process of a DAST crystal using the prism coupled Cerenkov phase matching (PCC-PM) method. THz waves were generated efficiently using the d133 process, and the magnitude of the nonlinear optical coefficient d133 estimated from the THz intensity ratio was 34.1 pm / V. These results indicate that PCC-PM can be used to examine unevaluated d-values of NLO crystals and estimate their values.
