Ultrafast Mirrors Ultrafast Mirrors

Ideal for use with broadband femtosecond pulses
High reflectivity over a very broad band:
      +/-50 nm @ 800 nm
  or +/-20 nm @ 400 nm (the second harmonic)

 Low group delay dispersion (GDD).
 Optically robust with a high damage threshold.
 Both 45o and 0o angle of incidence (AOI) are available.
  s-pol at 45
o gives higher reflectance, broader operating range and smaller GDD.
  Use s-pol when possible.

Substrate: BK7 or UVFS glass, Dia 1" x 6 mm or Dia 2" x 8 mm.
