A narrow light beam that propagates in the atmosphere with less disturbance than conventional light beams ia introduced. The, operating method and features of the newly proposed log-range nondiffracting beam (LRNB) are briefly demonstrated. Some experimental results of the atmospheric propagation of this beam at 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.#1999 OCIS codes: 010.1300, 010.1330,010.3310.
