I present the results of research, on the generation of terahertz (THz) radiation under the action of femtosecond laser pulses on liquid nitrogen (LN). Our experimental results supported by theoretical interpretation, showed that under femtosecond laser radiation, liquid and gas emit THz waves in a very different way. We assume that the mobility of ions and electrons in liquid can play an essential role, forming a time-dependent quasi static electric field. We discuss the influence of the phase transition of LN from gas to liquid and then to supercritical fluid on the properties of the THz wave generation.
