TTB RANGE
The TTB range of mirrors is based on a specialist coating design to offer a broader reflectivity bandwidth than the TTS range while maintaining a good Group Delay Dispersion (GDD) and high Laser-induced damage threshold (LIDT). At 800nm, mirrors from the TTB range achieve an LIDT of >=0.45 J/cm2 in 25fs and >=1.15 J/cm2 in 500fs. For LIDTs relating to other pulse durations please do not hesitate to contact us, we are happy to advise you.
