Medical lasers are specialized devices that use focused light to treat various medical conditions. They work by emitting a specific wavelength of light that can be absorbed by different tissues in the body. This allows for precise targeting of areas, making them useful in procedures like laser surgery, skin resurfacing, and eye surgery. These lasers can cut, coagulate, or vaporize tissue, depending on their settings and the type of procedure. They are commonly used in dermatology, ophthalmology, and dentistry, providing benefits such as reduced bleeding, minimal scarring, and quicker recovery times compared to traditional surgical methods.
