Abstract
A narrow light beam that propagates in the atmosphere with less
disturbance than conventional light beams is introduced. The
operating method and features of the newly proposed long-range
nondiffracting beam (LRNB) are briefly demonstrated. Some
experimental results of the atmospheric propagation of this beam at a
distance of 500 m are shown in comparison with a conventional
collimated beam and a focused beam. The results and related
analyses show that the LRNB is much less influenced by atmospheric
turbulence than other beams and suggest that the LRNB can apply to many
fields.
