Frequency calibration in the ArF excimer laser-tuning range using laser-induced fluorescence of NO.
A frequency calibration in the tuning range of the ArF excimer laser near 193 nm was performed. Different electronic spectra of NO were measured by laser-induced fluorescence in a cell and in an oxyacetylene flame. Spectra were measured with a frequency-doubled and Raman-shifted dye laser system and with a tunable ArF excimer laser with a modified configuration. A list of absolute frequencies of the B(2)II(upsilon' = 7) ? X(2)II(upsilon'' = 0) and D(2)Sigma(+)(upsilon' = 0) ? X(2)II(upsilon'' = 1) transitions in this spectral region is given, including a more comprehensive assignment of the latter excitation spectrum.
