Description
CaF2 Optical Crystal
Description
Calcium fluoride(CaF2) is a very important optical functional crystal, which has good optical properties, mechanical properties and chemical stability. It can be used as optical crystal, laser crystal and inorganic scintillation crystal. It has a wide transmittance range (0.125-10 μm), and is widely used as optical medium from vacuum ultraviolet to mid infrared. CaF2 crystal is an ideal optical material for achromatic lenses because of its special refractive index and relative dispersion. At present, deep UV excimer laser lithography is developing from 193 nm to 121 nm. CaF2 single crystal has the advantages of good ultraviolet transmittance, high laser damage resistance threshold, low stress birefringence and high refractive index, which makes it the best choice for the research of deep UV excimer laser lithography. In terms of laser applications, laser diode pumped CaF2 crystals activated by Er3+, Tm3+, Yb3+ and other 3-valent rare earth ions were obtained at room temperature.
