© 2021, Springer Science+Business Media, LLC, part of Springer Nature.We establish the conditions under which collisions of electrons with ions affect the generation of terahertz radiation at normal incidence of a laser pulse on a dense plasma in a constant magnetic field. If during the time of exposure to the laser pulse, the number of collisions of electrons occurred is not small, then the amplitude of generated magnetic field decreases, the shape of the generated pulse changes, and the total energy of terahertz radiation decreases. The influence of collisions on the generation of terahertz radiation manifests itself in a relatively weak magnetic field, when the electron cyclotron frequency is lower than the plasma frequency.
