Development of a Stable Oxygen Sensor Using a 761 nm DFB Laser and Multi-Pass Absorption Spectroscopy for Field Measurements
An optical sensor system based on wavelength modulation spectroscopy (WMS) was developed for atmospheric oxygen (O(2)) detection. A distributed feedback (DFB) laser with butterfly packaging was used to target the O(2) absorption line at 760.89 nm. A compact multi-pass gas cell was employed to increa...
