optimizations can be performed empirically. e presented mirror has been designed
for a titanium–sapphire laser, and a pulse duration of 19.1 fs was achieved. e LIDT of
the mirror was also measured in an Son1- procedure at a central wavelength of 790nm
and pulse duration of 30 fs (Angelov etal. 2011) with 0.3 J/cm

. e currently published
results suggest that the inuence of the material can be transferred for the chirped mir-
ror fabrication. Chirped mirrors with high gap materials in the high refractive index
layers show a higher LIDT than the comparable materials with a lower gap in the respec-
tive layer ...
