Abstract: An arrangement for the resonant frequency doubling of multimode laser radiation with resonators is provided, including mirrors and an optically nonlinear material. The arrangement ensures a dispersion-free tuning of the length of a passive resonator, and enables the frequency doubling of a multimode laser, which is resonant simultaneously for all modes of the laser radiation, and which is achieved by pairs of mutually oppositely disposed movable elements of an optically transparent material, such as prisms (P1, P2). The prisms are brought into the beam path of the resonator (R), formed from mirrors (M1 to M4) and optically nonlinear material (BBO). The prisms are movable elements (P1, P2) which are connected to adjusting elements such as piezoactuators, so that the optical length of the resonator (R) can be tuned and compensation for dispersion attained.

The first and second components are movable with respect to each other such that the first and second detent elements can form a detent connection. The assembly unit is able to assume a not correctly locked state in which the first and second detent elements are in immediate vicinity of each other, but have not yet formed a detent connection, and a correctly locked state in which the first and second detent elements have formed a detent connection. A checking device is provided so as to be integrated into the assembly.

Abstract: The invention concerns the embodiment of panel loudspeakers working according to the bending wave principle. Said loudspeakers are generally formed by at least one acoustic panel (11) and at least one driver (12), the driver (12) being connected to the acoustic panel (11). When such acoustic panels (11) are used for reproducing low frequency audio signals, the acoustic panel (11) must be arranged in sufficiently large sound walls in order to exclude the occurrence of an acoustic short circuit between the front part and the back part of the panel. Apart from being costly, only one side of the sound walls is actively used for sound generation as a result of the separation of both acoustic panels (11). Hence, the invention aims at providing a panel loudspeaker (10) that does not require any additional sound walls in order to exclude the occurrence of an acoustic short circuit while at the same time enabling full utilization of the surface of the acoustic panel (11) for sound generation.

Abstract: A method for determining the fatigue strength of a corrodible connecting part between at least two structural parts, with the connecting part being subjected to specified corroding surroundings and a given repeated mechanical strain while being used. Diagrams (stress-number curves) that represents the variable of the repeated strain in relation to the number of strain repetitions until the destruction of the connecting part are used in order to determine the fatigue strength. First, a strain-free pre-corrosion of the connecting parts is carried out in a corrosive atmosphere corresponding to the corrosive atmosphere during the intended use of the part, in a time period after which the duration of the pre-corrosion has hardly any influence on the shape of a stress-number curve that is recorded subsequently.
