The molecular ionization spectra of BaO and LuO were recorded in low-temperature natural gas-air flame with excitation laser wavelengths in the range 440–480 and 535–575 nm. Addition excitation of barium and lutetium monoxides by a second laser quantum did not amplify the ionization signal. One-step laser excitation with wavelengths of 549.3 and 466.2 nm is optimal for BaO and LuO, respectively.
