2940 nm (2.94 µm) Er:YAG Lasers

2940 nm corresponds to the absolute peak absorption of liquid water and hydroxyapatite in nature. Er:YAG lasers emitting at 2.94 µm produce explosive vaporisation of water molecules with near-zero collateral thermal spread, making them the premier technology for dental hard-tissue drilling, dermatological skin resurfacing, and orthopedic bone surgery.
