Abstract: A reference harmonic absorption curve of a laser absorption spectrometer can have a reference curve shape derived from a reference signal generated by the detector in response to light passing from the laser light source through a reference gas or gas mixture. The reference gas or gas mixture can include one or more of a target analyte and a background gas expected to be present during analysis of the target analyte. A test harmonic absorption curve having a test curve shape is compared with the reference harmonic absorption curve to detect a difference between the test curve shape and the reference curve shape. Operating and/or analytical parameters of the laser absorption spectrometer are adjusted to correct the test curve shape to reduce the difference between the test curve shape and the reference curve shape.

Arrangements for adjusting beam cross-sectional area and angle are optionally provided. Methods which can be performed on such an apparatus and computer program products for performing such methods are further provided.
