Nd: YLF Description
Nd:YLF stands for Neodymium-Doped Yttrium Lithium Fluoride. It is a laser crystal that has been doped with neodymium ions (Nd3+). Nd:YLF crystals are used as gain media in solid-state lasers.
Nd:YLF crystals are valued for their ability to produce high-quality laser beams in the infrared (IR) region of the electromagnetic spectrum. They are used in a variety of applications, including Medical Applications, Scientific Research, Materials Processing, and Remote Sensing.
