Abstract

Study on focus characteristics of the laser beam for long distance propagation in atmosphere is very important for many laser applications, especially for lightcraft vehicle, laser weapon. In this paper, the influence of atmospheric turbulence and thermal blooming on focus characteristics of laser beam is given for several typical lasers with different wavelength. The excursion of the laser beam axis for long distance propagation in atmosphere is also obtained for several laser beam axes. The calculations coincide with the experimental result.
