Large-aperture adaptive optical system for correcting wavefront distortions of a petawatt Ti : sapphire laser beam

This paper reports a large-aperture adaptive optical system with a bimorph deformable mirror and Shack – Hartmann wavefront sensor for aberration correction and beam focusing improvement in state-of-the-art petawatt Ti : sapphire lasers. We consider methods for providing feedback to the wavefront se...
