ABSTRACT:
A transparent pressure foot for use with laser welding and cutting systems and the like. The transparent pressure foot is positioned by means of a mount so that it makes contact with a surface with a predetermined force. The foot is composed of a material that is transparent to the laser energy at its particular frequency. The foot has a top surface for receiving the laser energy and a bottom surface for making contact with the surface. The laser energy is transmitted through the transparent pressure foot and is focused to a point below the bottom surface of the pressure foot. This permits pressure as well as laser energy to be applied to the same point on the surface to facilitate laser welding or cutting.
