(a) Simultaneously recorded single-scan time-correlated oxygen signals. The curves correspond to 138, 304, and path-integrated concentrations of oxygen, equivalent to path lengths in air of 0.5, 1.1, and , respectively; (b) typical multimode diode laser spectrum around ; (c) evaluated vs set path-integrated oxygen concentrations in air, plotted with a linear fit.

Recording of the reinvasion of ambient air into a previously nitrogen-flushed glass container covered by polystyrene foam slabs of (a) and (b) thickness, respectively. An offset path-integrated concentration of , due to the air outside the container, was subtracted from the signals.
