LBO Nonlinear Optical Crystal.jpg


BaF2(Barium Fluoride) is a crystal that has good transmittance over a wide spectrum range of 150nm-12.5um. It is transparent from the UV to Infrared, from 150-200nm to 11-11.5um. It has been used for functions in windows for infrared spectroscopy such as fuel oil analysis, lenses, prisms and especially UV transmittance. High grade BaF2 can even be used for scintillation crystals, where it is one of the fastest for the detection of x-ray, gamma-rays, and high energy particles.


Of note, BaF2 is used for cross-polarized wave generation (XPW) with Z[001] or holographic [011] crystallographic orientation. XPW generation is a non-linear 3rd order process where the generated wave has the same frequency as the incident wave but is perpendicularly polarized. Other applications of BaF2 is the detection of 511keV gamma photons in positron emission tomography (PET),  preopacifying agent in enamel and glazing frits production and as welding agents.
