Standard Femtosecond laser optics
Coatings for a 120-150nm bandwidth in a range of 600-1000nm wavelengths.
Very high reflectance mirrors (R>99.99%). High dispersion mirrors and pairs can reach negative GDD (Group Delay Dispersion) of some hundred fs2 and can be used for pulse compression.
Center wavelength, GDD and TOD (Third Order Dispersion) on demand. Positive as well as negative TOD can be achieved.
Spectral tolerance ± 1 % of center wavelength.

Gires-Tournoi Interferometer (GTI) mirrors

LAYERTEC also offers GTI mirrors for the Ti:Sapphire wavelength range and for other femtosecond lasers in the NIR spectral range. Compared to prism compressors, GTI mirrors reduce the intra-cavity losses resulting in higher output power of the laser.
