Holmium doped Lithium Yttrium Fluoride


Holmium doped Lithium Yttrium Fluoride (Ho:YLF or LiYF4:Ho3+) single crystal rods are designed to be applied in solid-state lasers which are widely used for industrial, medical and scientific applications. Pure YLF crystals are transparent within the spectrum band of 0.12 – 7.5 µm, photo-, thermo- and adiation-resistant. The YLF crystals have low values of non-linear refraction index and thermo optical constants, which makes theses crystals applicable in areas as research, development, education, production, photonics, optic, laser technology and telecommunications. Typical applications for Er:YLF, Ho:YLF, Tm:YLF products:

  • Highly sensitive detection/ranging measuring systems (Ho:YLF, wavelength – 0.75 µm and Er:YLF, wavelength – 0.85 µm)
  • Eye-harmless target spotlighting laser system (Er:YLF, wavelength – 1.73 µm)
  • Complex measuring systems using several operation wavelengths:
    (Er:YLF, wavelength 0.85 and 1.73 µm)
    Ho:YLF, wavelength 0.75 and 0.98 µm)
    (Tm:YLF, wavelength 2.35 and 1.89 µm)
  • Guidance systems lasers (Ho:YLF, wavelength 3.9 µm)
