Quasi-monochromatic gamma-ray beams are produced in the laser Compton slant-scattering at the Shanghai Laser Electron Gamma Source (SLEGS) of the Shanghai Synchrotron Radiation Facility. A high-power CO(2 )laser is operated in Gated CW mode in a wide range of pulse repetition frequencies of 1-100 kHz and pulse width > 1 mu s. The Gated CW operation of the CO(2 )laser generates pulse gamma-ray beams with a variety of time structure and gamma flux. We report fundamental laser properties in the Gated CW operation and the gamma flux in two cases of gamma-ray beams suited to nuclear physics experiments and industrial applications.
