Abstract
A high-energy beam is precompensated by a process including receiving a high-energy beam from a source and energy from a target. The target energy includes wavefront aberrations related to atmospheric and other external disturbances encountered along a distance separating the target. A correction signal is determined responsive to the high-energy beam and the target energy. The correction signal is also configured to pre-compensate for wavefront aberrations related to the atmospheric and other external disturbances and to cancel aberrations introduced by the adaptive optics techniques. A wavefront of the outcoupled high-energy beam is adjusted responsive to the determined correction signal. A beam control system includes three adaptive optics servo loops and an aperture-sharing element. The arrangement is adapted to self-cancel internal optical-path-difference errors in the outcoupled beam and to pre-compensate the outcoupled beam according to a conjugate of the wavefront aberrations related to atmospheric and other external disturbances.
