Abstract

The interest in Free electron Laser is due to: its large wavelength range, which at present extends from about one centimeter to 0.24 micrometer; its tunability; its high peak power"2 This point is illustrated in Fig. 1, which cornpares the FELs and other radiation sources: microwaves tubes, lasers, undulators in high brightness synchrotron radiation storage rings, plasma based X-ray lasers at Livermore and Princeton. The FEL performance level is partly based on experirnental data, and partly extrapolated from our present knowledge of the physics and technology of this system. This second case applies in particular to the far TJv and soft X-ray region. One can see that there are two main regions of interest for FELs applications, where they can be superior to other sources: one in the IR and millimeter to centimeter region; the second in the short wavelength region, below 0.1 micrometer. In this paper we will discuss the present status of the research to produce a FEL in the short wavelength region, and the characteristics and performance of such a system.
