摘要: Atomic oxygen generated in a discharge flow tube is detected at 630.03 and 636.38 nm using intracavity dye-laser spectroscopy. This the first reported observation of these highly forbidden transitions absorption. It demonstrated that absolute concentration measurements can be made with The sensitivity relative to conventional absorption spectroscopy enhanced by factors ranging from 3500 17,000, depending on laser power. At highest sensitivity, atomic should detectable 5-cm path length densities 10(15)-10(16)/cm(3).
