Unlike synchrotrons with multiple beamlines, free-electron lasers (FELs) are single-beam facilities, which nevertheless have a number of endstations. The latter requires development of complex radiation transport line, which should be efficient enoug

The effect of an external longitudinal magnetic field on the optical free induction decay from a free radical is observed for the first time. The experiments were performed on a rotational transition of the hydroxyl radical, OH (2Π3/2(J = 1) ← 2Π

Pulse-periodical free electron lasers with an optical cavity can have a fine and always have a hyperfine spectral structure of radiation due to the coherence of output pulses, which are parts of different or the same intra-cavity light pulse, respect

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 i
