The paper presents the current state of research on the generation of terahertz radiation in the optical breakdown of gases by laser radiation, consisting of the fundamental and second harmonics of femtosecond laser radiation. We consider the main approaches to describing the generation of terahertz radiation. The influence of the focusing mode, spatial and temporal modulation, changes in the wavelength, and polarization state of the pump radiation is shown. Also considered is the influence of the properties of the medium into which laser radiation is focused.
