The phase conjugation between the deformable mirror and the wavefront sensor in the aberration correction of a terawatt Ti:sapphire laser is studied experimentally and theoretically in this paper.At varying values of phaseconjugation precision,we focus the corresponding beams into spots of the same size of 5.1 μm× 5.3 μm with a f/4 parabola in the 32 TW/36 fs Ti:sapphire laser system.The results show that the precision of conjugation can induce an intensity modulation but does not significantly affect the wavefront correction. The phase conjugation between the deformable mirror and the wavefront sensor in the aberration correction of a terawatt Ti: sapphire laser is studied experimentally and theoretically in this paper. A varying value of phaseconjugation precision, we focus the corresponding beams into spots of the same size of 5.1 μm × 5.3 μm with af / 4 parabola in the 32 TW / 36 fs Ti: sapphire laser system. The results show that the precision of conjugation can induce an intensity modulation but does not significantly affect the wavefront correction.
