  • Fluoride Laser Crystals: LiYF4(YLF) - SPIE

    Fluoride crystals are among the most important hosts for laser materials because of their special optical properties. Of these, LiYF 4 (YLF) is one of the most common rare-earth-doped laser materials, with a variety of efficient mid-IR laser lines from the UV (Ce 3+ :YLF) to mid-IR range.

  • Nd:YLF Fluoride Crystal

    Description. Neodymium-doped Lithium Yttrium Fluorides (Nd:LiYF4 or Nd:YLF) is a crystal which lasers at 1047 nm and 1053 nm wavelength.Its main advantages are: large fluorescence line width, low thermal lensing, low threshold for CW applications and naturally polarized oscillation, which makes Nd:YLF an excellent material for CW, mode locked operation.

  • LiYF4 (YLF) single crystals doped with rare-earth

    Also upconservation laser action in YLF and YLF:Er crystals is reported. More recently YLF doped with rare-earth elements has gained some attention. Pulsed room-temperature laser action at 2.06 micrometer has been achieved using YLF:Ho sensitized with Er and Tm. Using YLF:Pr blue light emission at 479 nm at room temperature was observed.

  • Pr:YLF crystals | 4Lasers

    Only few laser materials have necessary properties for realization of lasing in visible spectral range. Trivalent praseodymium (Pr 3+) is known to be an interesting laser ion for using with solid-state lasers in the visible spectral range because of its energy levels scheme, providing several transitions in the red (640 nm, 3 P 0 to 3 F 2), orange (607 nm, 3 P 0 to 3 H 6), green (523 nm, 3 P 0 ...
