| Outline of Final Research Achievements |
Cavity ring down spectroscopy method was used to measure atmospheric hydro peroxy radical (HO2). 1506 nm laser which is generated from injection-seeded optical parametric generator was focused into cavity ring down cell and output light leaking from the cavity was monitored by high speed photo detector. Limit of detection for absorbance of 3.7×10-10 cm-1(1s) was achieved, which is corresponding to 100 ppt for atmospheric HO2 concentration.
