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/cm.sup.2 to about 10 J/cm.sup.2 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.
