Femtosecond applications require mirrors when a temporal pulse broadening effect is undesirable.
Metallic mirrors do a good job, but if you need a higher LIDT and better reflectivity, Low GDD Ultrafast Mirrors are better. These are designed for a certain wavelengths and angle of incidences (AOI). They are often used in applications that provide external beam manipulation for Ti:Sapphire, Yb:YAG and YB:KGW and Er:Fiber laser fundamental wavelengths, as well as their harmonics.
We design and manufacture mirrors in-house for high LIDT, high reflectivity and low Group Delay Dispersion (GDD) values. Each coating batch is tested to confirm their reflectivity and GDD characteristics. We can measure GDD values in a wavelength range of 500 – 1650 nm with a resolution of up to 5fs². LIDT measurements are carried out on request at independent companies.
