Nd:YLF
Nd:YLF features an extremely large fluorescence line width, low thermal lensing effect and natural polarization. It is widely used in mode-locked lasers, continuous lasers and material processing fields. As an alternative medium to Nd:YAG, Nd:YLF is used to work in the near-infrared region, generating lasers at wavelengths of 1047nm and 1053nm. It can be applied in linearly polarized resonators, mode-locked lasers, diode-pumped Nd:YLF lasers and Ti:sapphire chirped pulse amplifiers.

Natural polarization
Extra-wide fluorescent line width
High ultraviolet transparency
The thermal lensing effect is smaller than that of YAG crystals
Continuous lasers have a relatively low excitation light threshold
Suitable for medium repetition frequency, high average power Q-switched mode-locking operation
Effective single-mode operation, high power output and low beam divergence anglemore -
TLF(TbLiF4)
TLF has similar transparency range to TGG. It should be noted that this material show improved absorption at the shorter wavelengths. Unlike TGG, color center formation and cation valence changes are minimized in the fluoride crystals resulting in a consistent “water-white” appearance. This is promising for optical isolators for visible wavelength lasers.
Transparency range: 400-1500 nm
Verdet constant (rad / T · m): 38
Refractive index (1064 nm): no=1.4679, ne =1.4962
Absorption @ 1064 nm：~ 0.02 % / cm
Nonlinear refractive index：~ 1 × 10-19 m2 / Wmore -
