Erbium-Doped Lithium Yttrium Fluoride Crystal

Data sheet

Density	3.95 g/cm³
Materials	Er:YLF Crystal

More info

Erbium-Doped Lithium Yttrium Fluoride (Er:YLF) Crystal has a low phonon frequency, enhancing luminescent quantum efficiency by minimizing non-radiative multi-phonon relaxation. Its long-lived laser emission levels allow for higher energy storage, making it ideal for Q-switched lasers. The broad transparency range from VUV to 10 μm, combined with a negative thermo-optic coefficient, reduces thermal lensing effects and ensures stability in high-power applications. Heeger Materials provides Er:YLF Crystal for advanced applications.
