    Abstract: A surface-emitting semiconductor laser is described, with a semiconductor chip (1), which has a substrate (2), a DBR-mirror (3) applied to the substrate (2) and an epitaxial layer sequence (4) applied to the DBR mirror (3), said layer sequence comprising a radiation-emitting active layer (5), and with an external resonator mirror (9) arranged outside the semiconductor chip (1). The DBR mirror (3) and the substrate (2) are partially transmissive for the radiation (6) emitted by the active layer (5) and the back (14) of the substrate (2) remote from the active layer (5) is reflective to the emitted radiation (6).

    Abstract: A semiconductor laser device (5) comprising at least one semiconductor laser chip (7) is provided, wherein the semiconductor laser chip (7) contains an active layer that emits electromagnetic radiation. Further, at least one corner reflector (1) is formed in the semiconductor laser chip (7). The corner reflector (1) has a first and a second reflective surface (14, 15), wherein the first and the second reflective surface (14, 15) are arranged at an angle of less than 90 degrees with respect to one another. This results in an improved emission characteristic of the radiation emitted by the semiconductor laser device (5).

    Abstract: For determining the relative humidity of a highly moist gas, particularly air exiting from a wood-drying apparatus, there is used a humidity sensing arrangement having a capacitive sensor, whose capacitance varies with changes in the relative humidity of gas to which it is exposed, and means for generating an output signal proportional to the prevailing capacitance of said capacitive sensor. The capacitive sensor is exposed to a heated partial flow of the highly moist gas, and the output signal of the output signal generating means is modified in correspondence with the extent to which the partial flow has been heated.
