Infrared laser-absorption spectroscopy (IR-LAS) sensors play an important role in
diagnosing and characterizing a wide range of combustion systems. Of all the laser …

Great efforts have been dedicated during the last decades to the research and development
of hypersonic aircrafts that can fly at several times the speed of sound. These aerospace …

Laser absorption spectroscopy (LAS) has been rapidly developed and widely applied to
combustion diagnosis in recent decades. As a cost-effective tool for measuring multiple …

We present a practical implementation of calibration-free wavelength-modulation
spectroscopy with second harmonic detection (WMS-2f) for measurements of gas …

Tunable diode laser absorption spectroscopy (TDLAS) has become a proven method of
rapid gas diagnostics. In the present review an overview of the state of the art of TDL-based …

The development and initial demonstration of a scanned-wavelength, first-harmonic-
normalized, wavelength-modulation spectroscopy with nf detection (scanned-WMS-nf/1f) …

Diode laser based absorption spectroscopy (DLAS) is widely used for gas detection in
variety of applications across the energy, petrochemical and mining industries. Recent …

A mid-infrared laser absorption sensor was developed for gas temperature and carbon
oxide (CO, CO 2) concentrations in high-enthalpy, hydrocarbon combustion flows. This …

A tunable diode laser (TDL) temperature sensor is designed, constructed, tested, and
demonstrated in the exhaust of an industrial gas turbine. Temperature is determined from …

We present broadband dual frequency comb laser measurements of pure H 2 O absorption
(natural isotopic abundance of 99.7% H 2 16 O) from 6600 to 7650 cm− 1 (1307–1515 nm) …
