A multi-pass pumping scheme for thin disk lasers consisting of dual parabolic mirrors with conjugated relationship is presented. The anti-disturbance ability of pumping is analyzed by ray tracing method under different kinds of disturbances. Both theoretical and experiment results show that disturbances in this system won't lead to a misalignment of each pumping spot, but only the position of superposed pumping spot on disk crystal will be changed. Compared with the multi-pass pumping scheme consisting of parabolic mirror and folding prisms, this pumping scheme has a better anti-disturbance ability.
