We have proposed a new scheme for polarized positron production, consisting of two quantum processes i.e. inverse Compton scatterings of circularly polarized laser light on high-quality electron beams and successive electron-positron pair creations. Using a circularly polarized laser beam of 532 nm scattered off a high-quality electron beam with the energy of 1.28 GeV, we have demonstrated for the first time productions of highly polarized positrons positrons with an intensity of 2 × 104 e+/bunch and an average energy of 36 MeV. Hence an average polarization of positrons was determined as 73±15(stat)±19(syst)% by means of a newly designed positron polarimeter.
