A Laser-Compton Gamma-ray beamline in SAGA-LS has been planned to investigate the nuclear science and technology. The electron beam energy of 1.4 GeV and a small emittance are attractive to generate an intense and narrow energy bandwidth of Laser-Compton gamma-ray beam in MeV-region. Thus a design work for a gamma-ray beamline has been performed. Since the electron energy will be fixed, 1.4 GeV, for SR users, the laser wavelength should be variable to tune the energy of the gamma-ray beam. An OPO-DFG laser is one of candidate for this purpose. However, the laser power is not high enough to obtain the gamma-ray yield of -10(6) photons/s/100mA. The other method to tune the energy of gamma-ray beam is selecting the scattering angle by using a collimator and an absorber. However, simulation shows that the collimator-absorber scheme produce a poor bandwidth of the gamma-ray beam. An acceptable performance beam can be obtained by controlling the energy of electron beam at present stage.
