How TDLAS Works TDLAS technology leverages the narrow linewidth and tunable characteristics of semiconductor lasers to target the specific absorption lines of oxygen molecules. By modulating the laser frequency, the emitted beam passes through the gas sample and is selectively absorbed by oxygen, causing attenuation of the transmitted light intensity. The attenuated signal is detected and demodulated at the receiver and combined with the Beer-Lambert law to derive the real-time oxygen concentration.
