Ultrafast Laser Mirrors

Low GDD Ultrafast Mirrors are designed to handle high peak powers, provide reflectance greater than 99.8% and GDD is sligthly negative. All of this makes these mirrors ideal for femtosecond laser systems, like Ti:Sapphire, where pulse broadening is a concern.
Ultrafast laser line mirrors are designed to cover popular Yb:KGW, Yb:KYW, Yb:YAG and Ti:Sapphire laser lines with reflectance of more than 99.9% and at the same time to maintain |GDD| to be as close to 0 fs2 as possible.
GTI mirror is a kind of dielectric dispersive mirror with a spatial variation of the layer thickness values. Such mirrors are used for dispersion compensation in mode-locked lasers, for example. GTI mirrors featuring broadband behavior with GDD down to -2000 fs2 per bounce for your femtosecond laser system.
