Abstract: According to the theorem proposed herein, if we put a phase-matched plate at the near-field of CO<sub>2</sub> laser array, it can restrain the far-field off-axis lobes output energy of laser beam. In addition, we use the parameter <i>M</i><sup>2</sup><sub>x</sub> to evaluate the laser beam quality. In this paper,<span style="font-family: DFKai-SB;"> when<span style="font-family: DFKai-SB;"> a phase-matched plate is used to near-field, energy can centralize to 92.92%, and the beam quality <i>M</i><sup>2</sup><sub>x</sub> of far-field is 5.63. The phase-matched plate not only can centralize energy more efficiently but also can improve the beam quality quite substantially. </span></span>
