The invention relates to an ignition device for an internal combustion engine (10), in particular of a motor vehicle, having a laser device (26) which has a lasing solid body (44) and generates a laser beam (24), preferably in the form of a laser pulse, for radiation into a combustion chamber (14), wherein the laser device (25) is assigned focusing optics (52) for focusing the laser beam (24). According to the invention, the laser beam (24) has a beam profile which deviates from the circular shape. A pumped light source is provided for loading the laser device with pumped light. The beam profile of the laser beam and/or of the pumped light has a rectangular or linear shape and/or a circularly annular shape and/or a convex shape.

The invention relates to a gripper (1), in particular a Bernoulli gripper for holding two-dimensional components such as silicon-based wafers (2) with a low degree of loading, having a clamping ring (4) connected to a controllable robot arm (3), having a baffle plate (6) which is connected to the clamping ring (4) by means of a funnel-shaped component (5) and has a gripping face (7) which communicates with a flow system (8) which passes through the funnel-shaped component (5) and the baffle plate (6) and by means of which, after an excess pressure has been applied to the Bernoulli gripper (1), a negative pressure is to be produced on the gripping face (7) of the baffle plate (6) in order to attach by suction the wafer (2) to be gripped, having a rubberized bearing surface (9) of a bearing ring (10) which is integrated in the gripping face (7) and provides a slip-resistant movement of the wafer (2) attached to the gripping face (7) by suction, and having a sensor (11) for detecting the wafer (2) attached to the gripping face (7) by suction. In order to permit an extremely shock-resistant attachment of the wafer to be gripped on the gripping face of the gripper, the invention provides a damping device (12) which is circumferentially adapted to the gripper (1), the contour of which device, as viewed in the plan view of the gripper (1), protrudes circumferentially above the contour of the latter, and which device forms such a damping resistance for the wafer (2) to be gripped during its suction-induced approach towards the gripping face (7) that the wafer (2) comes to bear in a shock-free manner against the rubberized bearing surface (9) of the bearing ring (10).

The invention relates to a gripper (20) for contactlessly holding and precisely positioning a disc-shaped or plate-shaped object (31, 32), which has a holding device (21) for generating a holding force acting essentially perpendicular to the principal plane of extension of the object (31, 32). To this end, the gripper (20) has positioning nozzles (22), which are separate from the holding device (21) and which are provided for generating a positioning force acting essentially parallel to the principal plane of extension of the object (31, 32) by means of a fluid exiting the positioning nozzles (22).

The gripper device has a Bernoulli pick-up device (4), stops (10) for laterally supporting a plate held by the pick-up device and at least one planarizing nozzle (5) subjected to compressed gas. The lateral stops are guided under spring action in a bearer for the Bernoulli pick-up device and planarizing nozzle.

The laser has a pulsed pumped light source (30) formed by pumping diodes (3). A solid laser crystal is enclosed into a resonator (9), and a quality switch increases power density. A focusing device (7) focuses a Peltier cooling section (12) to a cooling mechanism (11) for cooling the resonator. The mechanism has cooling systems, where the Peltier cooling section is assigned to one of the cooling systems for cooling the diodes.
