Nd:YLF (Neodymium-doped Yttrium Lithium Fluoride), Nd:YLF Crystal

Product Code : CO-Nd:YLF-2N-CU

Nd: YLF crystal is an important near infrared laser material. It can generate 1047nm and 1053nm wavelength lasers, and pump lasers with a wavelength of 755nm-811nm. It can be used as gain media for laser oscillators and preamplifier. Because it has better performance than Nd: YAG in single mode, high stability and so on, it can replace Nd: YAG crystal.

ATT grows Nd:YLF using Czochralski method with high quality starting materials for crystal growth and precise inspection of scattering particle assures the quality of crystals.. We inspect the whole boules with interferometry and their scattering particles with He-Ne laser. Nd:YLF is an excellent crystal that is very suitable for mode-locking to obtain short-pulse lasers. Its thermal lens effect is very small, the fluorescence line width is wide, and it outputs linearly polarized light. Nd:YLF crystals have gained important applications in inertial confinement laser fusion research projects.
