Abstract
A new dynamic alignment procedure, with a high repetition rate, taking into account all the fluctuations of the components of each laser beam, including the driver, is proposed, using the driver itself. Diode pumped solid state drivers, operating at 1 - 10 Hz, allow the alignment in thermal stabilized thermal conditions and its control until the main shot. An alignment sensor designed for such a procedure is presented. It is based on a set of two CCD cameras with their optics, located behind the last spatial filter pinhole, a set of boresights inserted at the pinhole locations and an image processor. This equipment fulfills the requirements in terms of delay, precision and reduction of the number of components.
