Er:YAG laser rod. An Er:YAG laser (erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium-doped yttrium aluminium garnet (Er:Y 3 Al 5 O 12). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light. [1]
YAG, like garnet and sapphire, has no uses as a laser medium when pure. However, after being doped with an appropriate ion, YAG is commonly used as a host material in various solid-state lasers. [8] Rare earth elements such as neodymium and erbium can be doped into YAG as active laser ions, yielding Nd:YAG and Er:YAG lasers, respectively.
Soft tissue applications with erbium lasers feature less hemostasis and coagulation abilities relative to the CO 2 lasers. Er,Cr:YSGG laser was found to be effective in gum de-pigmentation. [13] The new CO 2 laser operating at 9,300 nm features strong absorption in both soft and hard tissue and is the newest alternative to erbium lasers. [14]
Fractional CO2, Nd:YAG, and Erbium are three different types of common lasers available for treating under-eye bags, however, you should talk to your dermatologist to decipher which one will be ...
Erbium–ytterbium and Erbium-doped glass lasers: 1.53–1.56 μm Flashlamp, laser diode Erbium-ytterbium and erbium-doped glass lasers are made in rod, plate/chip, and optical fiber form. Common uses for Er:glass lasers include rangefinding and skin resurfacing. Erbium doped fibers are commonly used as optical amplifiers for telecommunications.
Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
Erbium is a chemical element; ... utilize erbium ion's 2940 nm emission (see Er:YAG laser), which is highly absorbed in water (absorption coefficient about 12 000 /cm).
Laser rods (from left to right): Ruby, Alexandrite, Er:YAG, Nd:YAG The active laser medium (also called a gain medium or lasing medium ) is the source of optical gain within a laser . The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously ...
