    Er YAG Laser Crystals

    Description


    Erbium-doped Yttrium Aluminum Garnet (Er:YAG) is a pale green crystal with various output wavelength. Typically, highly doped Er:YAG, about 50% Yttrium atoms replaced by Erbium, is used as laser medium for 2940 nm wavelength. Due to the strong water and human body fluid absorption at this wavelength, Er:YAG laser has a wide dental and medical applications.

    For example, low doped Er:YAG, about (0.1~1)% Yttrium atoms replaced, plays an efficient role in generating high power 1600 nm 'eye-safe' laser. The excellent optical and mechanical properties and a wide pump band of 600~800 nm make Er:YAG an ideal laser crystal.


    Features
    • Works in a relatively eye-safe wavelength region
    • Strongly absorbed by water, hydroxyapatite and human body fluid
    • Wide pump band from 600~800 nm
    • Works well under room temperature
    • High slope efficiency
    • Good optical quality

    Applications

    • Medical laser systems including skin disorder therapy, hard tissue removal, blood sugar monitoring, orthopedics
    • Dental laser systems including tooth enamel, cosmetic surgery
