A kind of new phase aberration correcting method is introduced—using a phase countervailing mirror to correct t he low-frequency phase error. This method is mainly aimed to correct the static phase aberration caused by the fishing error on the optics. With random phase screen simulating the low-frequency phase aberration of the amplifiers, and the other effect of amplifiers on the beam is neglected, a beam propagation is setup. A new concept of equivalent phase plate is introduced and the phase of the mirror, as the invert phase of the equivalent phase plate, is easy to get. Finally, simulation of the correcting course was done.
