The considerable progress in understanding the free electron lasers (FEL) physics made it an actual task now to find the ways of practical FEL application. The broad wavelength FEL tunability allows it to be used in laser chemistry or for fundamental spectroscopic research. But there is a problem -- the radiation line of the undulator, the key element of the FEL, is too broad for some chemical or spectroscopic application. The wavelength width may be narrowed by using frequency selective elements, e.g., the planar quartz plates may be inserted in the optical cavity or may be used as the external selective element. In the frame of the tentative agreement between OKB Granat and Duke University FEL Laboratory the design of broad band tunable Fabry-Perot cavity for infra red range was developed which allowed the user to select narrow spectral line and to monitor its parameters during operation. There are a lot of Fabry-Perot cavities with removable elements on the base of a set of invar or quartz rings which allows changing of the basic frequency in a small range. In this paper we propose the design of broad band tunable Fabry-Perot cavity for infra red range from 2 to 4 mkm with mode variation from 40 to 240 GHz.
