The Novosibirsk Free Electron Laser (NovoFEL) facility is able to produce high-power tunable terahertz (THz) laser radiation in quasi-continuous mode. The ability to control/shape this THz radiation is required in a number of user experiments. In thi

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

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

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

A comprehensive analytical optimization of the design and geometrical parameters of the hybrid optical resonator for the KAERI compact terahertz free-electron laser (KAERI FEL) is considered. Our calculations show that the three optimization stages o
