摘要
A method of operating a laser and a gas analyzer to reduce low frequency and high frequency power non-linearity errors passes a laser beam through a sample gas to a detector. Intensity measurements are taken and compared to a reference set of measurements. The reference set of measurements can be calculated by measuring pressure and temperature of the sample gas. The laser wavenumber tuning width is locked to tune a high frequency of an absorption path fringe to a predetermined reference value. T he analyzer can be operated without taking a reference set of measurements and the analyzer is much smaller than previous analyzers.
