Ultrafast Mirrors

Ideal for use with broadband femtosecond pulses
High reflectivity over a very broad band:
+/-50nm @ 800nm
or +/-20nm @ 400nm (the second harmonic)
Low group delay dispersion (GDD).
Optically robust with a high damage threshold.
Both 45^o and 0^o angle of incidence (AOI) are available.
s-pol at 45^o gives higher reflectance and smaller GDD.
Substrate material: BK7 or UVFS glass.
