Abstract : It is shown that a beam of light can be deflected continuously through large angles along a curved path using the gas flow from a convergent-divergent nozzle sector whose throat lies on the arc of a circle. The amount of deflection depends on the included angle of the nozzle sector and on the density gradients created by the expanding gas flow. For a 360 deg included angle the beam can in principle be bent into a closed path with a radius of the order of a few tens of centimeters. Nozzle sectors with included angles of 30 deg and 180 deg are studied both theoretically and experimentally.
