Abstract
A gas measurement system as disclosed can include a coherent light source, which emits a light beam; a detector; a beam path formed between the light source) and the detector; and a gas cell arranged in the beam path such that the detector receives light transmitted through the gas cell. The gas cell can include a porous ceramic and have an optical path length which is a multiple of the actual layer thickness of the gas cell. A optical element can be arranged in the beam path between the light source and the gas cell with the light beam emitted by the light being widened and unfocussed as the light beam enters the gas cell.
