Abstract
We propose a method for compensating phase dispersion in chirped pulse amplifier systems which is based on adaptive optics. By placing a feedback-controlled arbitrarily deformable mirror in the stretcher where frequency components are highly dispersed, arbitrarily high- order phase dispersion within the amplifier can be canceled by introducing the appropriate phase delay. To demonstrate this concept, we model a 10 fsec chirped pulse amplifier and show that transform limited pulses are obtainable. We also show that deleterious effects such as angular beam divergence and spatially dependent broadening are negligible. Finally, we discuss design considerations for a 1D adaptive optic mirror.
