Application of an adaptive mirror system for high intensity experiments with MBJ multi-terwatt Ti:sapphire laser

摘要

The quality of the laser beam wave front is one of the most important parameters limiting the laser intensity available for laser-matter interactions. Modern Ti:Sa lasers deliver powers of tens of terawatts for a duration of ～ 30 fs; the corresponding pulse energy level in excess of 1 Joule requires crystals of > 20 mm diameter.
