Gires-Tournois Interferometer (GTI) Mirrors

Gires-Tournois Interferometer (GTI) Mirrors

  • Greater than 99.8% Reflectivity for S and P Polarization
  • GDD Values from -250 to -600fs2
  • High Damage Thresholds

Gires-Tournois Interferometer (GTI) Mirrors are optical standing-wave resonators primarily used in chirping applications such as pulse compression. Gires-Tournois Interferometer Mirrors, also known as GTI mirrors, utilize a partially reflective front surface and highly reflective back surface to generate chromatic dispersion. This design allows for higher laser output power and stability than comparable prism or grating pulse compressions systems by featuring lower losses and sensitivity to errors in system alignment. Although ideal for use with Yb:YAG or Yb:KGW femtosecond lasers, GTI mirrors can be optimized for use with other laser systems, including Ti:Sapphire.
