of background organics, mostly aromatic compounds. Normally, these deposits are
removed by oxygen in the air when excited by the laser pulse.
It turns out that the fs LIDTs of oxide lms also change with ambient gas composition
and pressure (Nguyen et al. 2011), although for reasons dierent than those discussed
for ns pulse exposure. Figure 5.13 shows that the multiple-pulse damage uence in vac-
uum drops to about 10% of F
1
at atmospheric pressure. e single-pulse thresholds are
unaected by pressure, and there is little dierence in the F
th
(S) curves for S < 1000.
