Pump-probe experiment is widely used spectroscopic method. In case using different frequencies and different sources for pumping and probing there practically are no limitations on time duration of phenomena under investigation. But if using the same source for pumping and probing time range is limited by length of optical scheme from picoseconds to few nanoseconds. By using NovoFEL emission time range of pump-probe experiments can be extended up to hundreds nanoseconds in optical region from infrared to terahertz.
