ND:YLF Laser Crystal Rod used at 1047nm and 1053nm
ND:YLF Laser Crystal Rod used at 1047nm and 1053nm
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.
Main features:
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 angle；
