Abstract: Optical apparatus includes an acousto-optic medium and an array of multiple piezoelectric transducers attached to the acousto-optic medium. A drive circuit is coupled to apply to the piezoelectric transducers respective drive signals including at least first and second frequency components at different, respective first and second frequencies and with different, respective phase offsets for the first and second frequency components at each of the multiple piezoelectric transducers.

Abstract: A method for manufacturing includes applying patterned electromagnetic energy to each of a sequence of layers of a dry film comprising a photosensitive material so as to create in the photosensitive material in each of the layers a respective two-dimensional (2D) pattern corresponding to a slice of a predefined three-dimensional (3D) structure. The layers in the sequence in which the respective 2D pattern has been created are laminated together to produce a multi-layer stack. The multi-layer stack is developed so as to remove the photosensitive material in which the 2D pattern has not been created, thereby forming the 3D structure.

Abstract: A method for fabrication includes providing a substrate having an upper surface with pattern of one or more recesses formed therein. A laser beam is directed to impinge on a donor film so as to eject droplets of a fluid from the donor film by laser-induced forward transfer (LIFT) into the one or more recesses. The fluid hardens within the one or more recesses to form a solid piece having a shape defined by the one or more recesses. The substrate is removed from the solid piece. In some embodiments, the recesses are coated with a thin-film layer before ejecting the droplets into the recesses, such that the thin-film layer remains as an outer surface of the solid piece after removing the substrate

Abstract: A method for disposing material includes positioning a donor film including a donor material at a predefined distance from an acceptor substrate, the donor film facing toward the acceptor substrate. One or more pulses of laser radiation are directed to impinge on the donor film at a given location so as to induce formation of a protrusion made from the donor material. A distal tip of the protrusion touches the acceptor substrate and disposes thereon while the protrusion is still in contact with the donor film. A spot of the donor material is formed on the acceptor substrate by increasing a separation between the donor film and the acceptor substrate so as to detach the distal tip of the protrusion from the donor film.
