Tunable diode laser absorption spectroscopy (TDLAS) has been widely employed in atmospheric trace gases detection. In th......
The wavelength modulation indices are measured based on harmonic amplitude ratio of 4f_(amp)/6f_(amp) (4f_(amp) and 6f_(......
Behaviors of harmonic signals in wavelength modulation spectroscopy (WMS) for gas detection with Lorentzian line under h......
We experimentally demonstrate a simple modulation-free scheme for offset locking the frequency of a laser using buffer g......
Real-time adaptive noise cancelling for signal-to-noise enhancement in direct absorption spectroscop
An adaptive filter for cancelling noise contained in the direct absorption spectra is reported. This technique takes adv......
Investigation of self-adaptive algebraic tomography for gas reconstruction in larger temperature ran
We develop a self-adaptive algebraic tomography algorithm (SAATA) to investigate the simultaneous reconstruction of conc......
Tunable diode laser based gas detectors are now being used in a wide variety of applications for safety and environmenta......
A CO2 sensor for capnography, based on a hollow...
A novel measurement system for the gas density based on spectrum absorption is studied in details. Based on the theory o......
Tunable diode laser absorption spectroscopy (TDLAS) is a new method to detect trace-gas qualitatively or quantificationa......
Influence of the quantum-confined Stark effect on the temperature-induced photoluminescence blueshif
Measurements of the excitation power-dependence and temperature-dependence photoluminescence (PL) are performed to inves......
Operating a laser diode in an external cavity, which provides frequency-selective feedback, is a very effective method t......
