Optical imaging techniques are ubiquitous for the resolution of non-uniformities in gas flows.
Planar imaging techniques such as laser-induced fluorescence are well established and …

An in situ thermometry technique was developed for low-pressure flames based on laser
absorption spectroscopy of nascent carbon dioxide. Discrete, rovibrational lines within the ν …

The design and demonstration of a tunable diode laser sensor for in situ temperature and
water (H 2 O) measurements in laboratory flames is presented. A newly-designed probe …

We demonstrate a step change in the capability of diode laser excited two-line atomic
fluorescence (TLAF) thermometry and show it is well-suited to the study of low-pressure …

The use of diode lasers for spatially resolved temperature imaging is demonstrated in low-
pressure premixed methane–air flames using two-line atomic fluorescence of seeded …

Nonlinear excitation regime two-line atomic fluorescence (NTLAF) is a laser-based
thermometry technique that has application in turbulent flames with soot. However, no …

The feasibility of using degenerate four‐wave mixing (DFWM) for hot gas thermometry in the
mid‐infrared spectral region is, for the first time, demonstrated by probing molecular ro …

We demonstrate quantitative measurements of methane (CH4) mole fractions in a low-
pressure fuel-rich premixed dimethyl ether/oxygen/argon flat flame (Φ= 1.87, 37 mbar) using …

We highlight the capabilities and potential of diode laser induced fluorescence for
measurements in gas-phase reacting flows. Many applications of diode lasers in practical …

In this Letter, we demonstrate, for the first time (to the best of our knowledge), calibration-free
imaging of full-frame temperature fields for particle-laden flames using two-line atomic …
