Nd:YLF — Nd-doped Lithium Yttrium Fluoride
Features
Nd:YLF crystal, also known as Nd-doped lithium yttrium fluoride, is a lithium yttrium fluoride crystal that produces 1047nm and 1053nm lasers. The main advantages of Nd:YLF crystal are: super large fluorescent linewidth, low thermal lens effect, continuous laser application Lower excitation light threshold, natural polarization, etc. Therefore, Nd:YLF crystal, neodymium-doped lithium yttrium fluoride is an ideal laser crystal material for continuous laser and mode-locked laser. The Nd:YLF crystal we provide, Nd-doped lithium yttrium fluoride grown by Czochralsky method, can provide Nd:YLF crystal rod or Nd:YLF crystal plate with different doping concentration.
