Abstract
The first lasing of the Beijing FEL was reported at the 1993 FEL Confe rence. After improving the performance of some components, saturation of the system was achieved in December 1993. The main measures adopted will be discussed in this report. First, the original undulator was r eplaced with a new one with better characteristics. Second, back-bomba rdment of the thermionic cathode microwave gun was reduced by deflecti ng magnet. With these and other modifications, saturated power output of 10(8) over the spontaneous emission was obtained. Saturation over t he wavelength range 9-11 mu m was achieved.
