Product Description:
TLF has similar transparency range to TGG. It should be noted that this material show improved absorption at the shorter wavelengths. Unlike TGG, color center formation and cation valence changes are minimized in the fluoride crystals resulting in a consistent “water-white” appearance. This is promising for optical isolators for visible wavelength lasers.
