A new scheme of H- charge-exchange injection without stripping foils is proposed. It is composed of a neutralizer of the H- beam using Lorentz stripping, the colliding system of a high power laser and the H0 beam to excite H0 atoms to the 3P state using the Rabi oscillation, and a magnet to strip the H0(3P) to a proton beam by Lorentz stripping. The necessary laser wavelength, laser power, magnetic-field gradient, and maximum magnetic field are estimated for a beam energy from 1.0 to 3.0 GeV. The result shows that such a scheme is sufficiently feasible for H- beams with an energy discussed here.
