In laser propagation in the atmosphere, the wavefront of laser beam will be distorted by the atmospheric turbulence. The wavefront aberration can be compensated with the stimulated Brillouin-scattering (SBS) effect. In this paper, an outdoor experiment is presented. In the experiment, a ruby oscillator and an amplifier are used as source; a laser beam travels from the source to a reflector; which simulates a target; the reflected laser beam travels through the atmosphere and is focused into a SBS cell by a lens; finally the phase conjugate light produced by the stimulated Brillouin scattering (SBS) effect return to the target. The distance between the target and the SBS cell is 70 m. The Output energy of the ruby laser is 2 J. The laser beam spot and the phase conjugate light spot are recorded by a camera at the target. The result of the experiment shows that: the wavefront aberration is compensated in the process of laser beam and the phase conjugate light travels between the target and the SBS cell.
