This research aims at improving the detection sensitivity of heterodyne electrooptical sampling (EOS) .In order to improve detection sensitivity, we tried to realize heterodyne EOS using DAST crystal having electrooptical constant larger than lithium niobate crystal which has been used for heterodyne EOS so far.Also, measurements were made using the DAST crystal bonded to the Si prism and the case where only the DAST crystal was used, and the results were compared.
