Gires-Tournois Interferometer (GTI) mirrors
Overview
Do you want top performance optimization for your Ti: Sapphire, Yb: KGW, Yb: KYW, or other femtosecond laser? OPTOMAN has a solution for you – the GTI mirror.
The GTI mirror is a 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.
OPTOMAN will design GTI mirrors featuring broadband behaviour with GDD down to -5000 fs2 per bounce for your femtosecond laser system.
Features
Absolute reflectance Rs>99.99% and Rp>99.99%
Absolute reflectance of GTI mirrors goes above 99.99% for the most demanding applications.
Highly Negative Group Delay Dispersion (GDD)
GTI Mirrors can be designed for any specific GDD requirement from slightly negative (-20 fs2) down to -5000 fs2.
Wide spectral bandwidth
In compromise to required reflectance and GDD values, broadband GTI Mirrors are feasible, as for example HR>99.8% at 760 - 840 nm with GDD=-200 fs2.
High Laser Damage Threshold
GTI mirrors are optimized for high resistance to laser irradiance with LIDT of >300 mJ/cm2 at 50 fs, 1030 nm, 150 kHz.
Custom - Negative Group Delay Dispersion (GDD) down to –5000 fss
- Mirrors with predefined and flat GDD.
- Spectral range from 250 nm up to 5000 nm.
- Diameter from 5 mm up to 120 mm.
- Coatings on substrates with positive or negative curvature.
