Transmitted light intensity versus time for a single sinusoidal scan of the laser wavelength with no CO absorption (left) shows that cavity noise is suppressed throughout the scan except for a small portion of time at the peak of the scan, when the scan rate is close to zero. Similar data, but with CO absorption (right) shows the shape of the scan for a 10 ppm CO concentration, a temperature of 1499 K, and a pressure of 1.51 atm.
