Abstract: A monolithic diode laser arrangement contains a plurality of individual emitters which are arranged adjacent to one another on a common supporting substrate and which in each case have contact windows for electrical contact which are arranged on the respective individual emitters on a front face opposite the supporting substrate. A method for producing such a diode laser arrangement and a laser device having such a diode laser arrangement are further described.

Abstract: For flip-chip mounting of a component with its contact surface on the contact surface of substrate, the component or the substrate is held at the free end of a lever arm which pivots around an axis, and the other part is held on a support. In a beam path between an optical device, especially a viewing device, and the contact surfaces of the two parts, a semireflecting mirror is provided to provide images of the two contact surfaces simultaneously in the optical viewing device. A first point on the one contact surface, a second point on the other contact surface, a third point on the mirror surface, and the pivot axis of the lever arm form the corners of a square. The beam path between the optical device and the semireflecting mirror is a beam path parallel to the optical axis of the optical device, the beam striking the mirror at an angle of approximately 45.degree..
