The 2940mm Wavelength Er:YAG laser is designed to work with a solid state setup that is sensible and easy to manage. This is made with a sturdy yttrium aluminum body that can handle light at a wavelength of around 2940 nm. This is infrared light and will be absorbed by water with ease. This makes it less common than Nd:YAG and Er:Glass lasers to use for many human skin controls. This is ideal for the treatment of acne scars and other serious problems that might be found on one's skin. This can also work with hydroxyapatite to make it easier for the unit to cut into bone tissues just like with soft tissues. This is useful for oral surgery procedures and can be made with sensible controls to see how it's designed.
