Abstract
A gas analyzer includes a calculator. The calculator calculates an intensity of one concentration signal based on an intensity of one frequency component of returned light yielded by multiply-modulated measurement light passing and coming back through a gas to be measured, or intensities of a plurality of concentration signals based on respective intensities of a plurality of frequency components of the returned light. The calculator calculates a measured value of concentration of the gas to be measured, based on the intensity of the one concentration signal or the intensities of the plurality of concentration signals.
