16 May 2007 Generation of 1.2 X diffraction-limited focal spot from the 100 TW Ti:sapphire laser system
Author Affiliations +
The wavefront aberrations in the 100 TW laser pulses are measured and corrected to improve the intensity distribution of the focal spot. Before correcting wavefront aberration of the laser pulses, the laser pulses have higher-order aberrations such as coma, trefoil, and spherical aberration as well as defocus and astigmatism. The wavefront aberrations in the laser pulses are corrected by the deformable mirror. 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.
