Abstract: A method can be used for operating an optoelectronic proximity sensor. The proximity sensor includes a radiation-emitting component, a radiation-detecting component and a control unit. The radiation-emitting component is operated by means of a pulsed current. During each measurement period, the pulsed current of the radiation-emitting component has an on-time and an off-time. The pulsed current has a pulse current intensity during the on-time, and the control unit evaluates a detector signal of the radiation-detecting component and lowers the pulse current intensity for a subsequent measurement period, when the detector signal exceeds a threshold value during at least one measurement period.

Abstract: Various embodiments may relate to a semiconductor laser device, including at least one laser diode, and at least one reflection surface which reflects diffusely and which is irradiated by the laser diode during operation, and an additional light-nontransmissive housing body having a cutout. The laser diode is the sole light source of the semiconductor laser device. The laser diode is mounted immovably relative to the at least one reflection surface. Light emitted by the semiconductor laser device during operation has the same spectral components as, or fewer spectral components than, light emitted by the laser diode. An interspace between the laser diode and the at least one reflection surface is free of an optical assembly. A light-emitting area of the semiconductor laser device is greater than a light-emitting area of the laser diode by at least a factor of 100.
