Abstract :
The wavefront aberrations in the 100 TW laser pulses are measured and corrected to improve the intensity distribution of the focal spot. The dynamic and static corrections are tested with the deformable mirror. When correcting wavefront aberrations with the deformable mirror, the focal spot having a 1.2 times spot size of the diffraction-limited focal spot is observed.
