We have observed for the first time wave front conjugation with amplified reflection return using the thermal nonlinearity of a thin film of nematic liquid crystal in conjunction with a low power laser (intensity on the order of 25 W/cm2). Self-oscillation is also observed.

    Two types of lasing in cholesteric liquid crystals (LCs) in the range of luminescence of laser dye molecules have been investigated. The first type belongs to the Bragg modes at the photonic band edge, which propagate along the normal to the LC layer. The second type of lasing is related to the...

    We have developed a new method for measuring tilt bias angles in spatially uniform and nonuniform thin films of nematic liquid crystals. The method employs modulation ellipsometry, based on the use of an exponentially decaying light wave to probe the boundary layer. Oscillations of the director...
