Nd:YLF

Nd:YLF

Neodymium doped yttrium lithium fluoride or Nd:YLF  is a solid state laser material which can be pumped with ARC lamp or laser diodes. Because of its relatively long fluorescence lifetime it can be used in Q-switched systems. One of main frequency-doubled Nd:YLF pulses application is to pump ultrafast Ti:Sapphire chirped-pulse amplifiers.

  • Various standard Nd:YLF rod sizes are available;
  • Optola offers only polished or AR coated rods;
  • Large rod and slab dimensions with non-standard dopant concentrations can be ordered by request.
