Creation of the HPLP system depends on solving such technical problems as: (a) generation of a laser beam with extremely small beam divergence at high power, (b) compensation for the laser beam distortions caused by atmosphere and by optical elements of the system. The technical solution of these problems defines the ultimate HPLP system design.
To compensate for beam phase distortions, dynamic holography techniques are considered, including phase conjugation. State-of-the-art laser systems with PC possess wide field of view, high responsibility, and high speed of response. In the chapter, the experimental data on phase conjugation of beam distortions of CO2 lasers by using such nonlinear medium as a sulfur hexafluoride are analyzed as applied to laser power transfer to space vehicle with onboard ASLPE.
The proposed laser adaptive optical system is based on the algorithm of compensation for the atmospheric optical distortion, which includes the following principal operation procedures:
generation of a reference coherent radiation source in an upper atmosphere to record the atmospheric distortions in the laser beam propagation path
generation of the high-power laser beam with a conjugated beam wave front by using a dynamic hologram-corrector that is recorded with the use of the reference source beam
