A. There are many lasers used for medical applications today and the one used to for this purpose is the holmium yag laser. This laser is preferred because the laser beam is delivered through a very thin fiber optic cable and does not have a high degree of tissue penetration at low power making it very safe. In other words, it primarily works where you point it and does not go deep into the tissue around the work site that could potentially damage uninvolved surrounding structures.
