emits light absorbed by water for precise tissue removal

The Er:YAG laser, short for Erbium-doped Yttrium Aluminum Garnet laser, is a type of laser commonly used in dermatology and dentistry for precise tissue removal and skin resurfacing. It emits light at a wavelength of 2940 nm, which is highly absorbed by water, making it effective for ablating both hard and soft tissues with minimal thermal damage to surrounding areas.
