Vortical structures of the chain-link-fence type have been experimentally produced in a plane jet. The jet was excited by temporal periodic disturbances with spanwise phase variations added in the initial shear layer. Chain-link-fence-like structures, which significantly differed from ordinary vortices such as “roller and rib” structures, are observed experimentally by stereoscopic particle image velocimetry when the temporal phase difference of disturbances with the spanwise direction is 180°. Some of the original vortices remain downstream as stretched lambda-type vortices, although the destruction of the orderly vortices into complex turbulence was significant.
