TTW RANGE

TTW RANGE

The TTW range of mirrors, like the TTB range, is based on a specialist coating design to offer a very broad reflectivity bandwidth based only on dielectric coating materials while maintaining a good Group Delay Dispersion (GDD) and high Laser- induced damage threshold (LIDT). As the LIDT of this mirror is very dependent on the application (pulse duration and pulse profile), please contact us for information on the LIDT, we are happy to advise you.
