  • Publication number: 20210032739
    Abstract: A method and apparatus for laser-induced forward transfer (LIFT) processing including a dynamic release mirror structure (DRMS) for desorbing delicate materials from a first surface and depositing a resultant formation of a portion of the materials on a second surface without damaging the material or coating the material with contaminants. The DRMS includes a lower-situated absorbing polymer layer on a transparent substrate. The lower-situated absorbing polymer layer is coated with a metal layer to reflect light of a laser pulse. The metal layer is topped by an upper-situated polymer cap layer. The 3-part layering of the metal layer sandwiched between the upper and lower polymer layers is variable in terms of materials and thickness to tune DRMS operational characteristics.
