Abstract
A method for operating an optical measuring system including a wavelength-tunable temperature-stabilized laser light source for measuring the concentration of a target gas in a measured gas, wherein an instantaneous base current Icorresponding to a wavelength λof a target gas absorption line is set so that a wavelength distance Δλdefined during calibration between a target gas absorption line for a target gas and a reference gas absorption line for a reference gas is maintained. During operation, a temperature difference in the laser light source, defined in advance during calibration, between the operating points selected at the time of calibration of the reference gas, with a base current I, and the target gas, with a base current I, is maintained by determining the required instantaneous base current Ifor the target gas, as a function of an instantaneous base current Ifor the reference gas.
