Abstract: A gas detection laser diode device and gas detection unit including the gas detection laser diode device having a hermetically sealed housing with electrical connectors at the bottom and a window, and inside the housing a laser diode and thermistor mounted on one stage of a thermo element. The thermo element is connected with the other stage to the base of the housing. Collimating means are arranged in the laser beam between the laser diode and the window. The window is tilted in respect to the axis of the laser beam such, that the ordinary reflection of the laser beam is steered off the laser beam axis and at least does not impinge on the laser diode. Preferably the collimating means and the laser diode are mounted on a same surface for holding them on the same temperature. The new device allows the detection of toxic gases with reduced detection limits over the prior art. The arrangement further claims a method to achieve reduced detection limits for gases.

Abstract: A combined gas sensor device allowing the measuring of the concentration of a gas by tunable diode laser spectrometry as well as by resonant photo-acoustics within one housing. A laser beam used for laser spectrometry is sent across the openings of a measuring cell usually used for resonant photo-acoustic determination. Thus, both measuring principles use the same gas sensing module with a minimum of space consumption, so that the device can be produced with minimum dimensions. Further, a common opto-electronics and electronics platform can be used which reduces the overall costs of such a combined gas sensor.
