Now we test main optical elements of the heterodyne scheme. For example, Fabry-Perot pulse extension system produces from 140 ps NovoFEL pulse extended pulse with duration of 10 ns at wavelength 119.3 µm and 15 ns at wavelength 163.3 µm. Heterodyne scheme, additionally to increasing of sensitivity, will be able to do calibration of absolute wavelength. This can be important in complicate experiments with multi-molecular medium where many close III. ACKNOWLEDGMENTS The study was supported by a grant of the Russian Science Foundation (project No 19-73-20060). The work was done at the shared research center SSTRC on the basis of the Novosibirsk FEL at BINP SB RAS, using equipment supported by project RFMEFI62119X0022.

N2 - The OH radical is a short-lived intermediate component in many important chemical reactions. The Novosibirsk free electron laser (NovoFEL) makes it possible to measure ultrafast spectral cinema of dynamics of this radical. In this paper, methods of increasing the sensitivity of such measurements by using a weak magnetic field and a heterodyne scheme are considered.
