Abstract

We have investigated laser ablation of molecular ions from the ferroelectric LiNbO3 at 532, 355 and 266 nm, comparing the effects of changing wavelength and intensity. The time-of-flight spectra show great sensitivity to the onset of plasma formation. Just below the plasma formation threshold, production of the monomer, dimer and trimer negative molecular ions were observed. Possible implications for thin-film deposition processing are discussed.
