Abstract :
As is known, light waves can reorient liquid crystals (LC). The magnitude of this reorientation provides information about the main energetic characteristics of the laser beam. An intrinsic interferometric process (leading, in particular, to the fringe pattern formation in the laser beam outgoing from the liquid crystal) provides precise all-optical method of reorientation measurement. Namely, the number of rings obtained in a beam with bell-shaped profile of intensity is determined by the maximal reorientation of the director in the center of the LC-cell which is directly related to the on-axis intensity
