    Abstract

    It is demonstrated that unique properties of orientational interaction of light with liquid crystals allow for high precision all-optical measurement of laser radiation intensity and determination of the focal spot location and its size. With that, non-absorptive character of the basic interaction phenomenon makes unperturbing measurement schemes feasible and ensures their applicability to high power beams. Large detector area and independent operation of its spatially distinct regions can be utilized to carry out parallel measurements for many beams.
