摘要： Printing apparatus (20) includes a donor supply assembly (30), which provides a transparent donor substrate (26) having opposing first and second surfaces and a donor film formed on the second surface so as to position the donor film in proximity to a target area (28) on an acceptor substrate (22). An optical assembly (24) directs multiple output beams of laser radiation simultaneously in a predefined spatial pattern to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate according, thereby writing the predefined pattern onto the target area of the acceptor substrate.

摘要： An optical scanner may include one or more acousto-optic deflectors (AODs) configured to deflect an optical beam along one or more scanning directions, where a deflection angle of the optical beam from the one or more AODs is controllable by one or more drive signals applied to the one or more AODs. The scanner may further include a dispersion compensator, where dispersion by the dispersion compensator at least partly compensates for dispersion by the one or more AODs to provide that the deflection angle of the optical beam at a particular configuration of the one or more drive signals is constant within a first tolerance for wavelengths of the optical beam within a wavelength range, and where at least one of the dispersion of the dispersion compensator or a transmittance of the dispersion compensator is independent of a polarization of the optical beam within a second tolerance.

摘要： An optical scanner may include a sampler to receive an optical beam and provide a sampled beam including a portion of the optical beam, a dispersive element to spectrally disperse the sampled beam along a dispersion direction, one or more detectors to receive at least a portion of the sampled beam dispersed along the dispersion direction, one or more acousto-optic deflectors (AODs) configured to deflect the optical beam from the sampler, and a controller. The controller may determine a center of mass of the sampled beam dispersed along the dispersion direction based on signals from at least one of the one or more detectors, and generate a drive signal for at least one of the one or more AODs to deflect the optical beam from the sampler along a selected deflection angle based on the center of mass.

摘要： 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.

摘要： Printing apparatus includes a donor supply assembly, which positions a transparent donor substrate having opposing first and second surfaces and a donor film formed on the second surface so that the donor film is in proximity to a target area on an acceptor substrate. An optical assembly directs one or more beams of laser radiation to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate. Means are provided to mitigate or compensate for the variation in reflection of the laser radiation across an area of the donor substrate, so as to equalize a flux of the laser radiation that is absorbed in the donor film across the area of the donor substrate.
