Abstract

Adaptive optics loops are now widely implemented on high power laser chains and several industrial solutions exist which are optimized for their specific constrains. However the main goal for adaptive optics loop implementation is to optimize the interaction between laser and matter (gas or solid). In particular, one parameter to optimize for loop convergence is the intensity at the focus of the off-axis parabola, which is the final optics seen by the laser. However it is in practice not possible to place any diagnostic directly in the beam in the interaction chamber. This is why the solution consists in creating a diagnostic beam from a beam pick-up somewhere upstream the focusing optics. The deformable mirror is then driven from the diagnostic beam wave front.
