Pol. VL - 10 IS - 4 SE - Articles DO - 10.4302/plp.v10i4.852 UR - https://www.photonics.pl/PLP/index.php/letters/article/view/10-37 SP - 103-105 AB - Using an external low-frequency electric field applied to dye-doped nematic liquid crystals, we demonstrate that random lasing obtained by optical pumping can be steered in angular direction by routing an all-optical waveguide able to collect the emitted light. By varying the applied voltage from 0 to 2 V, we reduce the walk-off and sweep the random laser guided beam over 7 degrees. <br /> <br /> Full Text: <a class="file" href="/PLP/index.php/letters/article/view/10-37/554" target="_parent">PDF</a> <br /> <br /> <strong>References</strong><ol><li>V.
