    Abstract: Techniques for laser processing of electrochromic glass or other thin-film devices where one or more layers are sandwiched between two thin-film conductive layers include directing a laser beam onto a first position on a surface of a workpiece. The laser beam includes substantially collimated pulses of electromagnetic radiation having an energy density from about 1 J/cm2 to about 10 J/cm2 in a spot having a characteristic dimension of at least about 5 mm at the surface of the workpiece. The laser beam removes the material from the first position, then is moved to a second position on the surface of the workpiece and removes material from the second position. The laser beam is then moved to one or more additional positions on the surface of the workpiece and removes material from the one or more additional positions.

    Abstract: The embodiments herein relate to methods for controlling an optical transition and the ending tint state of an optically switchable device, and optically switchable devices configured to perform such methods. In various embodiments, non-optical (e.g., electrical) feedback is used to help control an optical transition. The feedback may be used for a number of different purposes. In many implementations, the feedback is used to control an ongoing optical transition. In some embodiments a transfer function is used calibrate optical drive parameters to control the tinting state of optically switching devices.
