Phase distortion correction of Nd:glass laser radiation caused by turbulent long-length atmospheric trace to 2 km using phase conjugation

摘要

Abstract: In this paper, a possibility of precise correction of phase distortions due to inhomogeneities of turbulent atmosphere at a near ground surface path 2 km long is experimentally proved. Highly efficient transmission of laser radiation pulses of 20 nsec duration with energy up to 20 J through the path with nearly diffraction limited quality is achieved.!8
