keep almost the same size with following shots (Runkel etal. 1999). In Nd-doped laser
glass, micron-size platinum inclusions generate damage sites that rst grow but stabilize
in size at several hundred microns in diameter (Razé etal. 2003).
e exit surface damage growth has been generally described by an exponential
increase in diameter with the number of shots at xed uence (Figure 9.8):
