Er YAG, Erbium doped Yttrium Aluminum Garnet (Er:Y3Al5O12 or Er:YAG) combine various output wavelength with the superior thermal and optical properties of Er:YAG. It is an excellent laser crystal which lasers at 2.94μm. This wavelength is the most readily absorbed into water and hydroxylapatite of all existing wavelengths and is considered a highly surface cutting laser. It is a well known material for medical applications.

Er YAG laser Crystal—50% Erbium doped in YAG which can stimulate 2940nm laser used in medical and dentistry

The emission wavelength of Er YAG with doping concentration of 50% is 2940nm, which is at the position of water absorption peak and can be strongly absorbed by water molecules. Therefore, it is widely used in the field of plastic surgery and dentistry. At present, the projects we have participated in include laser blood collection instrument, which adopts the structure of both sides of Er:yag rods coated and xenon lamp end pumped.the Er YAG laser wavelength is an excellent choice for improvement of a variety of skin conditions and features of aging, including dyschromia, actinic photodamage, solar elastosis, acne and traumatic scarring, fine lines and mild to moderate rhytidosis, coarse skin texture, and skin laxity.
