✦ Synopsis

Rotational temperature of O a has been measured in an atmospheric-air furnace using KrF laser-induced fluorescence. Average measurement errors of 10.7% and 5.1% over a temperature range of 1325-1725 K were observed using two-and four-line excitation techniques, respectively. Ground-state depletion was observed for a spectral laser Jrradiance greater than approximately 7.5 x 106 W/cm 2 cm -1 . This technique is suitable for temperature measurements when the 02 vibrational population is not in thermal equilibrium.
