The present work aimed to study the variation
in the plasma parameters (temperature and density) of the
Ti plasma generated by 1,064 and 532 nm lasers at different
ambient N2 pressures for different delay times. The
characterization of the plasma-assisted pulsed laser ablation
of the titanium target is discussed. The emission
spectra of the titanium plasma produced in the present
study have been carefully investigated over the whole UV–
NIR (200–1,000 nm) spectral range. Boltzmann plots of
suitable spectral lines have been employed to derive the
excitation temperature, and the electron density is derived
from the Stark widths of the Ti II spectral line at
350.49 nm. |
