[16a-416-10] Two-dimensional coherent random lasing in photonic crystal fiber filled with dye-doped nematic liquid crystal

Keywords:random laser, liquid crystal, photonic crystal fiber

Laser oscillation was observed by irradiating excitation light to a sample filled with a dye-doped liquid crystal in the hole of the photonic crystal fiber.
It seems that the conditions under which the two-dimensional resonator type random laser oscillation occurs are prepared by strong light scattering due to a high refractive index of the liquid crystal.
It was also found that ON-OFF of laser oscillation can be controlled by phase transition of a liquid crystal.
