Laser-enhanced
molecular ionization spectrometry of BaO and LuO in low-temperature flame
Abstract
The
molecular ionization spectra of BaO and LuO molecules were registered in
low-temperature natural gas -air flame under laser excitation in the wavelength
ranges of 440-480 and 535-575 nm. It was shown that the amplification of
ionization signal is absent under additional excitation of barium and lutetium
monoxides by the second laser quantum. The optimal one-step excitation laser
schemes were proposed with wavelengths 549.3 nm for BaO è 466.2 nm
for LuO.
