Abstract: The present invention relates to a laser system and a method of generating a defined spatial mode-shaped laser beam using an unstable laser resonator layout. The laser system for mode shaping of a laser beam within an unstable optical resonator layout comprising an active medium, characterized in that, the active media comprises a pumped area, wherein the gain distribution is generated by an optical pump beam's spatially intensity profile. In a preferred embodiment, the system may further comprise an end-pumped layout to deliver the spatially shaped optical pump beam to the active medium; and/or an active element and/or a passive element for modifying the resonator losses; and/or means of output coupling of a laser beam from said unstable resonator layout. The system according to the present invention is suitable to deliver a top-hat beam profile.

Abstract: An elastic seal element seals a fluid passage between a first component and a second component from the surroundings, the fluid passage passing through the seal element. The seal element has a first bead, which provides a sealing line to sealingly contact the first component around the fluid passage. The seal element further has a second bead, which provides a second sealing line to sealingly contact the second component around the fluid passage. The seal element has a tubular shape, a tubular casing extending between the first bead at the first end of the seal element and the second bead at the second end of the seal element, wherein the tubular casing allows a transversal offset of the second bead relative to the first bead to seal the fluid passage by the seal element even when the second component is offset transversely relative to the first component.

Abstract: A connection arrangement (10) for electrically connecting at least one sensor (12) or actuator to at least one conductor track (22) on a circuit board (24) has at least one compression spring (18) for electrically conductive connection. The compression spring (18) is arranged between the at least one sensor (12) or actuator and the circuit board (24) so as to be under a mechanical preload. The compression spring has a contact end section (36) of the at least one compression spring (18) configured to rest against a contact plate (20, 70, 80, 90) that is electrically conductively connected to the conductor track (22). As a result, the connection arrangement (10) achieves a high level of electrical contact reliability and corrosion-resistance.
