Ultrafast Mirror, Low GDD, 380-420nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Low GDD Ultrafast mirrors are designed for femtosecond applications to provide an optimized performance from 380nm to 420nm with 0 degree or 45 degree angle of incidence (AOI). This is achieved by careful selection of coating stacks to combine high reflectivity and low GDD value from -10 fs² to 10 fs² at design bandwidth. Low GDD Ultrafast mirrors are intended for Ti:Sapphire, Nd:Glass, Er:Glass or Ytterbium doped host based lasers working in femtosecond regime.
