abstract = {<p style="text-align: justify;">The femtosecond laser ablation process and induced breakdown spectroscopy
of transition metal Ti in air background has been investigated systematically. The ablation
process is simulated by means of a three-dimensional two temperature model
(3D-TTM). The time-resolved spectroscopy is employed to determine the characteristics
of plasma during its evolution. The time-of-flight spectroscopy (TOFS) is also
used to characterize the plasma expansion. The evolution behaviors of the plasma and
its spectral characteristics have been analyzed as a function of pressure. It is shown
that the component, expansion behavior and characteristics of the plasma have strong
pressure dependences. The results are discussed in terms of the interaction mechanisms
between ambient air and plasma species.</p>},
