Chapter 14
shallow conical pits are large enough to remove damaged material and the surrounding
cracks. Care must be made when selecting the proper pit geometry to prevent excessive
downstream modulation. When done properly, the micromachined pit can have a sub-
stantially higher UV laser resistance than the original laser damage site. is is a very
interesting application of continuous-wave IR laser damage (laser ablation), creating
features that are laser resistant for nanosecond pulse UV operating lasers.
is same approach has been applied to multilayer interference mirror coatings.
However, mirror coati ...
