AB - We suggest an efficient XFELO having a new non-stationary out-coupling scheme. It consisted of two undulator sections located in sequence with a free space gap in-between. The first section is a conventional uniform undulator, the second one is a tapered undulator. At start time point X-ray radiation is basically produced by the uniform section. Mirrors of XFELO's optical resonator are calculated so that diffraction Q-factor reaches the highest value, i.e losses asre near to zero. As X-ray power increases the tapered undulator begins to bring more contribution in radiation power. Finally, at a new steady state regime all power is being produced by the tapered section. Because mirrors were optimized for Gaussian wavebeam to be produced in the first section, in the final steady state regime a portion of X-ray power will be out-coupled missing partly the mirrors.
