    摘要： A method of operating a laser drilling system to manufacture gravure printing plates without etching or the use of hazardous chemicals includes activating a laser drilling system, including a picosecond laser, light valves, and a mechanism adapted to rotate a gravure cylinder blank. Operation of the light valves, includes setting the light valves to block and/or allow pulses of laser energy propagating from the laser drilling system that can ablate a linear pattern of cells along a substantially entire length of the gravure cylinder blank. Drilling of cells includes targeting the laser drilling system on the gravure cylinder blank, such that ablation of materials occurs as sub-beams propagate along an optical path to the target area and impinge upon the gravure cylinder blank, wherein specific cells within the target area of the gravure cylinder blank are drilled or not drilled according to settings of the light valves.

    摘要： A system and method for aligning a microfilter in an optical circuit and thereby providing sub-beam impingement intensity control from a set of highly proximate sub-beams generated from a parallel process laser system removing a portion from a workpiece (exit holes in inkjet nozzle plates). The energy of laser-generated sub-beams to the target (cutting) point is attenuated to a level sufficient for maintaining operation of a charge-coupled-device camera below saturation when the sub-beams are incident on the camera, the CCD camera monitors the sub-beams and directs output to either a monitor or control computer. The microfilter is then adjusted to provide an optimal sub-beam pattern.

    摘要： A patterned, multi-layered thin film structure is patterned using ultra-fast lasers and absorption spectroscopy without damaging underlying layers of the layered structure. The structure is made by selecting ablatable layers based on their thermal, strength and absorption spectra and by using an ultra-fast laser programmed with the appropriate wavelength (λ), pulse width (τ), spectral width (Δλ), spot size, bite size and fluence. The end structure may have features (such as vias, insulating areas, or inkjet printed areas) patterned in the last (top) layer applied or at deeper layers within the layered structure, and can be used as components of organic light emitting didoes (OLEDs) and organic thin film transistors (OTFTs). The method of the present invention includes determining the product's specifications, providing a substrate, selecting a layer, applying the layer, patterning the layer and determining if more layers need to be added to the multi-layered thin film structure.
