COHR WP Ablation of BioPolymers 193nm.pdf

…chitosan films, at two different laser fluences.
Ablation Results
One of the first experimental tasks was to determine the laser ablation threshold at 193 nm. This was
accomplished by performing a series of etch rate measurements over a laser fluence range from 70
mJ/cm2 to a…

"The Pyrocam IV has three significant features," says McCauley. "First is
its large imaging array, measuring 25.6
mm2. Second is its small pixel size, which
measures at an 80 µm pixel pitch, resulting in the highest resolution thermal imager (320 × 320 pixels) that Ophir-Spiricon…

…is typically achieved,
resulting in about 25 new fills per year which are easily covered
e.g. by a 20 l premix gas bottle. In the measurement shown
in figure 2, after 4 weeks the reduction of energy is just about
30% with respect to the nominal pulse energy specification
