Abstract：
Beijing FEL facility has been built in IHEP, the saturated oscillation was obtained at a wavelength of 10.68 μm, on 28 Dec. 1993. The average output energy and the pulse width were measured to be 3 mJ, 2 μS, respectively. The corresponding oscillation power is greater than 220 kW, peak power is about 20MW, which is about 10⁸ times higher than that of spontaneous emission. The FWHM of the FEL spectral bandwidth is less than 2%. The small signal gain is 32% per pass. The extraction efficiency is 0.48%. In the present experimental results,BEFL can be saturated by changing electron energy at the wavelength range of 9-11 μm,the maximum average output energy and extraction efficiency are 10 mJ, 0.52% respectively, the minimum spectral bandwidth of 0.5% has been achieved by shortening cavity length.
