  • Light pulse positioning with dispersion compensation
    Patent number: 7821698
    Abstract: A light pulse positioning apparatus with dispersion compensation includes an acousto-optical device and a dispersive element optically coupled thereto. The dispersive element is placed and oriented in relation to the acousto-optical device to spatially and temporally disperse the light pulse and thus compensate, respectively, a spatial dispersion and a temporal dispersion caused by the acousto-optical device. The acousto-optical device can include one or more acousto-optical deflectors for one-dimensional or two-dimensional laser pulse positioning. The dispersive element can be a prism placed in front of the acousto-optical device. In a two-dimensional configuration, a single prism, if properly oriented, is sufficient for dispersion compensation of both acousto-optical deflectors.
