摘要

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 phase-conjugation precision,we focus the corresponding beams into spots of the same size of 5.1 μm x 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.
