Broadband Low GDD Ultrafast Mirrors 720-880 nm

  • High reflectivity and low group delay dispersion in broad region centered at 800 nm
  • Hard dielectric High Reflection or Ion Beam Sputtering coating
  • Laser Damage Threshold >50 mJ/cm2, 50 fsec pulse, 800 nm typical

EKSMA Optics offers broadband low GDD ultrafast laser mirrors are coated @ 720-880 nm. These ultrafast mirrors are designed to be used with 1st harmonic of Ti:Sapphire laser.

 

Standard mirrors feature high reflectivity (> 99 %), and even higher reflectivity (> 99.8 %) is specified for 082-7288HHR items (UV FS, Ø25.4 x 6 mm).
