LASER METHOD FOR TREATING ELECTROCHROMIC GLASS

Techniques for laser processing an electrochromic glass or other thin film device in which one or more layers are sandwiched between two thin film conductive layers include directing a laser beam onto a first location on a surface of a workpiece. The laser beam includes substantially collimated pulses of electromagnetic radiation having an energy density of about 1 J/cm2 to about 10 J/cm2 in a spot having a reference dimension of at least about 5 mm at the surface of the workpiece. The laser beam removes material from the first location, then moves to a second location on the surface of the workpiece, and removes material from the second location. The laser beam is then moved to one or more additional locations on the surface of the workpiece and material is removed from the one or more additional locations. 用于激光处理电致变色玻璃或其中一个或多个层夹在两个薄膜导电层之间的其他薄膜器件的技术包括将激光束引导到工件的表面上的第一位置上。该激光束包括在该工件的该表面处的具有至少约5mm的基准尺寸的光斑中具有约1J/cm2至约10J/cm2的能量密度的大体上准直的电磁辐射脉冲。该激光束从该第一位置移除材料，然后移动到该工件的该表面上的第二位置，并从该第二位置移除材料。该激光束然后移动到该工件的该表面上的一个或多个附
