A YAG laser, or Yttrium Aluminum Garnet laser, is a solid-state laser commonly used in various medical and industrial applications. It emits light at a wavelength of 1064 nanometers, making it effective for cutting, welding, and skin treatments. The laser operates by exciting the YAG crystal with a flashlamp or diode, producing a focused beam of light. In medicine, YAG lasers are often used for procedures like laser eye surgery and dermatology treatments. They can precisely target tissues, minimizing damage to surrounding areas. Their versatility and effectiveness make them a popular choice in both healthcare and manufacturing sectors.
