Abstract: An improved laser apparatus, inscribed in a parallelepiped rectangle R defined by a longitudinal axis, X, a vertical axis, Y defining a plane P and a lateral axis, Z, including a mounting means to mount the laser apparatus on a window, preferably a multi-glazed window, mounted in situ. The laser apparatus also includes a laser device generating a laser beam to treat a surface of the window, an orientation means able to orientate the laser beam defining a maximum decoatable surface WSm on the coated surface and a housing including an aperture to let the laser beam going out of the housing. The laser apparatus includes a skirt at least partially surrounding the aperture where the skirt is opaque to the laser beam. A related method is also described.

Abstract: An improved decoating apparatus and associated method inscribed in a parallelepiped rectangle defined by a longitudinal axis, a vertical axis, defining a plane and a lateral axis, including a mounting means to mount the decoating apparatus on a window mounted in situ. The decoating apparatus further includes a laser device to decoat at least partially a portion of a coating system presents on a surface of the window. The laser device includes a fixed part, irremovable in the decoating apparatus in directions paralleled to the plane and along the lateral axis, including a laser generator to generate a laser beam. The laser device includes a mobile part including a focal lens to produce a focal point of the laser beam at a defined distance from the focal lens. The decoating apparatus further includes a movable means able to move the mobile part substantially along the lateral axis.

Abstract: An improved decoating apparatus including a mounting means to be mounted on a multi-glazed window mounted in situ and a laser device to decoat at least partially a coating system present on a surface of the multi-glazed window. The decoating apparatus further includes a closing means at least partially to reduce the maximum decoatable surface to a working surface. Further, an associated decoating method and use of a closing means to decoat is disclosed.

Abstract: A method of calibrating a focal point of a laser apparatus inscribed in a parallelepiped rectangle R defined by a longitudinal axis, X, a vertical axis, Y defining a plane P and a lateral axis, Z. The method uses a laser apparatus for treating a window that includes a mounting means to mount a decoating apparatus on the window mounted in situ.
