摘要： An optically pumped semiconductor laser device having a surface-emitting vertical emission region (1) and at least one monolithically integrated pump radiation source (2) for optically pumping the vertical emission region (1). The semiconductor laser device is distinguished by the fact that the pump radiation enters the vertical emission region (1) in the form of partial bundles of rays of radiation with different radiation directions so that the pump radiation and the fundamental mode of the vertical emission region (1) have an overlap which is suitable for the excitation of this fundamental mode. This device is based on the fact that the fundamental mode of the vertical emission region (1) is preferably excited when the spatial intensity distribution of the pump radiation matches the profile of the fundamental mode.

摘要： A semiconductor component having a light-emitting semiconductor layer or a light-emitting semiconductor element, two contact locations and a vertically or horizontally patterned carrier substrate, and a method for producing a semiconductor component are disclosed for the purpose of reducing or compensating for the thermal stresses in the component. The thermal stresses arise as a result of temperature changes during processing and during operation and on account of the different expansion coefficients of the semiconductor and carrier substrate. The carrier substrate is patterned in such a way that the thermal stresses are reduced or compensated for sufficiently to ensure that the component does not fail.

摘要： A method is described for determining a rotation speed and a rotation direction of a component (2), in particular a transmission output shaft, with a sensor device (1). In the sensor device (1), as a function of a rotation speed and direction of the component (2), a first sensor signal and a second sensor signal are generated, which are phase shifted relative to one another and each of which, on reaching an upper switching threshold or a lower switching threshold in the sensor device (1), triggers a switching signal. When there are alternating, consecutive switching signals of the two sensor signals, the sensor device (1) emits a pulse signal as a function of which a variation of a sensor signal is generated, which is used to determine a rotation speed of the component (2). After a rotation direction reversal of the component (2) a pulse signal of the sensor device (1) is only generated after sensing a rotation movement of the component (2), this rotation movement of the component (2) being sensed when, in alternation, a switching signal of one sensor signal is followed by a switching signal of the other sensor signal.
