Abstract

We demonstrate what we believe to be the highest-contrast ( 10 11 ) , multiterawatt, chirped-pulse amplification (CPA) Ti:sapphire laser by applying the modified cross-polarized-wave (XPW) generation method. This method produces a contrast improvement of 3 orders of magnitude using microjoule input energy. Microjoule energy can be achieved by direct amplification without the complications of a double CPA system. The 10 11 contrast is sufficient for experiments on high-damage-threshold solid targets with focused intensities up to 10 22 W cm 2 .
