Er:YAG Crystals and Components

Lasers powered by Er:YAG (erbium substituted: yttrium aluminum garnet), operating at 2.94 microns, crystals couple well into water and body fluids. This is especially useful for applications in the fields of laser medicine and dentistry.

The output of Er:YAG enables the painless monitoring of blood sugar levels, while safely reducing the risk for infection. It is also effective for laser treatment of soft tissue, such as cosmetic resurfacing. It is equally useful for treating hard tissue such as tooth enamel.

Er:YAG enjoys an advantage over other laser crystals in the 2.94 micron range in that it employs YAG as the host crystal. The physical, thermal and optical properties of YAG are widely known and well understood. Laser designers and operators can apply their depth of experience with Nd:YAG laser systems to achieve superior performance from 2.94 micron laser systems using Er:YAG crystals.

Advantages of Er:YAG Crystal

* High slope efficiency
* Operate well at room temperature
* Operate in a relatively eye-safe wavelength range

Er:YAG Crystals was designed for 2.94 µm output wavelength Er:YAG is an excellent choice for Medical Laser Systems and Dental Laser Systems.
