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 the main applications of frequency-doubled Nd:YLF pulses is to pump ultrafast Ti:Sapphire chirped-pulse amplifiers.
