摘要：

A wavefront correction near the focus of a Pettawatt laser system is demonstrated. After correction, the Strehl ratio of focus is improved to 0.90, and the focal spot size using the f/4 off-axis parabola is reduced to 6.20 x 6.77 mu m(2). With full peak power, the peak intensity of 2.46 x 10(21) W/cm(2) is obtained.
