Nd:YLF is a laser active crystal that is doped with Neodymium ions and made from Lithium Yttrium Fluorides. It is known for its excellent laser performance, with high efficiency, good beam quality and broad spectral range. Nd:YLF is commonly used in high-power, continuous-wave (CW) laser systems, as well as in short-pulse laser applications, due to its low thermal lensing effect and high damage threshold. Additionally, Nd:YLF has a high emission cross-section, making it suitable for use in solid-state lasers, where high gain is required. Overall, Nd:YLF is a versatile laser crystal that is widely used in various industrial and scientific applications.
