Trace Methane Detection Based on Raman Spectroscopy Using a High Finesse Optical Resonator
Raman spectroscopy Methane detection Gas sensor
2009/6/8
A Raman spectroscopy-based gas sensor employing a high-finesse simple diode laser pumped external cavity, Power Build-up Cavity (PBC), has been developed. Results show that a compact 10-cm-long PBC in...
Near-IR diode laser-based sensor for remote sensing of methane leakage
wavelength modulation spectroscopy tunable diode laser spectroscopy methane gas sensor diode laser
2011/4/26
A tunable diode laser-based sensor for remote sensing of methane (CH4) leakage at a wavelength of 1.65 mm was developed. The 1.65 mm distributed feedback (DFB) diode laser has a narrow line width and ...
