Abstract
Using an external magnetic field, we demonstrate in-plane angular steering of a green pumped random laser in dye-doped nematic liquid crystals, where a near-infrared reorientational spatial soliton provides a smooth output profile with emission in a well-defined direction. By varying the orientation of the applied magnetic field, the soliton-guided random laser beam can be steered over an angle as large as 14°, corresponding to a transverse displacement of 0.49 mm at the output facet of a 2 mm-long sample.
