More info
Rare Earth Ions Doped Lithium Yttrium Fluoride (RE: LiYF₄) is a high-performance laser crystal with a tetragonal structure and uniaxial symmetry, enabling polarized laser output. Its low nonlinear refractive index minimizes thermal distortion, ensuring high-quality beams. Compared to YAG crystals, RE: LiYF₄ offers higher slope efficiency, lower threshold, reduced phonon energy, and longer fluorescence lifetimes. These characteristics make it highly suitable for high-power and precision laser applications.
