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] The 9,300 nm laser ablates hard tissue in excess of 5,000 °C, which often results in extremely bright thermal radiation. [15]
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 .
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.
Erbium's principal uses involve its pink-colored Er 3+ ions, which have optical fluorescent properties particularly useful in certain laser applications. Erbium-doped glasses or crystals can be used as optical amplification media, where Er 3+ ions are optically pumped at around 980 or 1480 nm and then radiate light at 1530 nm in
Laser gingivectomy is a dental procedure that recontours or scalpels the gingival tissue to improve long term dental health or aesthetics. [1] Compared to conventional scalpel surgery, soft-tissue dental lasers, such as laser diode, [2] Nd:YAG laser, [3] Er:YAG laser, [4] Er,Cr:YSGG laser, [5] and CO 2 lasers, [6] [7] can perform this procedure, offering a precise, stable, bloodless, often ...
Some commonly used lasers types in soft tissue surgery include erbium, diode, and CO 2. Erbium lasers are excellent cutters, but provide minimal hemostasis. Diode lasers (hot tip) provide excellent hemostasis, but are slow cutters. CO 2 lasers are both efficient at cutting and coagulating. [4] Laser surgery is commonly used on the eye.
