Calcium Fluoride for Femtosecond High Power Lasers Low Dispersion, Low B-Integral CaF2 Vacuum Windows Yb3+:CaF2 Laser Crystals

Low Dispersion, Low B-Integral CaF2 Vacuum WindowsCalcium fluoride features a very low spectral dispersion, a low non-linear refractive index and is available in sizes up to 440 mm diameter. These advantages make it a superior optical material for vacuum windows for spatial filters, target and compressor chambers. Calcium Fluoride properties

Yb3+:CaF2 Laser CrystalsLong fluorescence lifetime and broad absorption bands turn Yb3+:CaF2 into an ideal material for laser diode pumping. The material exhibits a low linear and non-linear refractive index and shows a broad fluorescence bandwidth supporting ultra short pulses less than 100 fs . Properties of Yb3+:CaF2 [1] D.
