Abstract

We argue that recent paper “Radially polarized terahertz radiation in laser-induced linear plasma wake” by Suyun Zhou and Yanfang Li [Optik 127 (2016) 3495–3498] is incorrect. These authors computed THz radiation from a plasma filament produced by a curl-free current. However it has been long known that curl-free current does not radiate.
