2940nm Laser

Diode laser VS Er:YAG laser Er:YAG lasers typically emit light with a wavelength of 2940 nm. the output of Er:YAG lasers is also absorbed by hydroxyapatite, which makes it a good laser for cutting bone as well as soft tissue.the output of an Er:YAG laser is strongly absorbed by water. This fact limits the use of this laser in surgery.Er:YAG lasers are far less common than their relatives diode laser. Diode laser is portable in size,affordable,very good for soft tissue surgery,the limit is can not applied to hard tissue
