The experimental device for generation of undulator radiation in terahertz wavelength region by use of undulator with ferromagnets is created. The device is based on a beam of a microtron with the energy 7.5MeV. The radiation wavelength is 200μ. Registered spontaneous radiation has a power 10 -6 W at a current of a beam 2mA in a pulse. With the optical resonator, in a mode, the amplification of 6 % is received, that in sometimes is more than the expected value. This effect is explained as a result of partial coherence of radiation. © 2010 American Institute of Physics.
