Abstract :
Development and applications of one-pulse time-domain spectroscopy on terahertz Novosibirsk free-electron laser is described. Spectrometer with Fabry-Perot etalon in reference branch is used for NovoFEL pulse diagnostics with measuring time of 0.4-0.5 ns. More long HCN-gas reference was applied for high resolution (38 MHz; 1.8·10-5) gas spectroscopy. Spectral resolution of the method as expected to be directly proportional to a measuring time.
