The first stage of Novosibirsk high power free electron laser (FEL) was commissioned in 2003. It is based on the normal conducting CW energy recovery linac (ERL). Now the FEL provides electromagnetic radiation in the wavelength range 120 - 230 micron. The maximum average power is 400 W. The minimum measured line width is 0.3%, which is close to the Fourier-transform limit. Four user stations are in operation now. Manufacturing of the second stage of the FEL (based on the four-turn ERL) is in progress.

12 MeV energy recovery non-superconducting linac of the Novosibirsk terahertz FEL is put into operation in 2003. The efficiency of energy recovery was studied. The transversal and longitudinal beam halo was investigated by studying the dependence of the beam dump current on steering corrector strength and RF system parameters. Ways to increase energy recovery efficiency are discussed.
