Description
Xu Lu and co-authors present a fast, single beam method to measure temperature with Raman scattering, in work from 2024. Hot, fast changing settings such as flames and plasmas need thermometers that are exact, quick, and simple. Their method uses air lasing, a laser like glow from air itself, as the probe.
The signal was strong enough for single shot readings a thousand times per second. Precision stayed tight across tested temperatures, though error grew as temperature rose. The glow's timing, spectrum, and beam shape make the single beam setup work. The team presents the method as a new route to high speed temperature checks in harsh flows.
