Abstract
A system for detecting a gas may include a first laser having a wavelength overlapping with two or more absorption features in a spectrum of the gas, a second laser having a wavelength centered away from absorbing features in the spectrum of the gas, and at least one sensor to determine a received power of the first laser and a received power of the second laser.
