High-temperature absorption studies of the Schumann-Runge band of oxygen at ArF laser wavelengths

摘要

The possibility of a simple single-shot oxygen monitor for a float-glass plant by use of the Schumann-Runge absorption lines within the broadband lasing structure of an ArF excimer laser initiated this detailed study. We present the theoretical predictions and the experimental absorption profiles at temperatures from 76 to 2000 degrees F. Laboratory experiments predict that detection of a few to ten parts per million of oxygen in the float section of the plant is doable.
