We propose a new scheme with “side-pumping” of laser-beams emitted from high-power laser diode arrays to an electron-beam in order to obtain high-power laser Compton gamma-ray. To calculate a gamma-ray flux in NewSUBARU of University of Hyogo, we measured powers, spectra and spatial characteristics of a typical GaAlAs laser diode array. Using the measured results and the data of electron beam at a beam line BL01 in NewSUBARU, we calculated a laser gamma-ray luminocity in the “side-pumping”. We conclude that the “side-pumping” scheme with a laser cavity to enhance Compton backscattering is expected to generate gamma-ray flux more than10⁸photons/sec.
