Outline of Final Research Achievements

High sensitive laser absorption spectroscopy system was developed to measure atomic oxygen number density using a forbidden line of OI 636 nm. Firstly, to detect the small transition probability line, integrated cavity output spectroscopy (ICOS) was developed. The sensitivity enhancement was estimated as 822 times by the ring down time measurement. As a result of microwave plasma diagnostics, the number density could be measured as low as 1.2×1021 m-3. Next, wavelength modulation spectroscopy (WMS) was combined with ICOS to increase the sensitivity. For the optimized modulation frequency, sweep frequency and time constant, the signal to noise ratio of WM-ICOS was increased 26 times as much as that of ICOS. This result shows the WM-ICOS system enables the number density measurement of atomic oxygen as low as 250 Pa.
