The 10B20EAG.2 Femtosecond Optimized Silver Mirror is 25.4 mm in diameter, 6.35 mm thick, and broadband optimized for 470 — 1000 nm. This ultrafast mirror is designed for zero to 45 degrees angle of incidence for S and P polarization. The absolute value of GDD is an astounding less than 5 fs2 from 550 to 1050 nm. Ideal for use with ultrashort pulse lasers, this high reflectance beamsteering mirror gives R>97% 470-1000 nm at 0 deg AOI, Rp>96% 480-1100 nm at 45 deg AOI and Rs>98% 460-890 nm or Rs>96% 430-1000 nm at 45 deg. Careful thin film coating design and advanced coating processes result in a mirror with maximum reflectivity and bandwidth with minimum effect on pulse dispersion.
