The 20B20EAG.1 Femtosecond Optimized Silver Mirror is 50.8 mm in diameter, 10 mm thick, and broadband optimized for 540 — 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>99% 600-1000 nm at 0 deg AOI, Rp>98.5% 580-1000 nm at 45 deg AOI and Rs>99% 540-1000 nm. Careful thin film coating design and advanced coating processes result in a mirror with maximum reflectivity and bandwidth with minimum effect on pulse dispersion.
