Yag laser
Yag Laser
Yag Laser (pronounced /jæɡ/), also known as Nd:YAG Laser, is a type of laser commonly used in various medical procedures. The term "Yag" is an acronym for Yttrium Aluminum Garnet (Y3Al5O12), the synthetic crystal that is used as a medium for the laser.
Etymology
The term "Yag" is derived from the chemical symbols of the elements that make up the synthetic crystal used in the laser: Yttrium (Y), Aluminum (Al), and Garnet (G). The "Nd" in "Nd:YAG Laser" stands for Neodymium, a chemical element that is doped into the YAG crystal to produce the laser light.
Usage
Yag Lasers are used in a variety of medical procedures, including eye surgery, hair removal, and lithotripsy. They are also used in dermatology for skin treatments and in oncology for tumor removal.
