※Long lifetime of 4F3/2 neodymium energy level
※Considerably softer and more brittle than is Nd:YAG
※Nd:YLF (a-cut) crystals that are used inside a laser optical resonator are self polarizing
※Custom crystals available upon request
Neodymium Doped Yttrium Lithium Fluoride（Nd3+:YLF） crystal is characterized by a long lifetime of 4F3/2 neodymium energy level. Compared to Nd:YAG, the lower thermal conductivity and a weak negative dn/dT lead to lower thermal distortions and allow to achieve a better output beam quality. Another distinctive feature is the high UV transparency, which is favorable for pumping with xenon flash lamps.
