## Abstract We have investigated the characteristics of the intense terahertz (THz) electromagnetic radiation in (GaAs)~35~/(AlAs)~35~ multiple quantum wells with an optical gating method, where the radiation source is coherent longitudinal optical (LO) phonons confined in the GaAs layers. It is fo
