We have demonstrated an intense plasma-based THz source using ~5 TW femtosecond laser pulses to irradiate solid targets. The energy of a single THz pulse emitted in the laser specular direction increases with the laser energy. The maximum THz energy can be as high as tens PJ/sr. The polarization of the THz pulse is measured to be linear.I.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
