Answer

Laser phototherapy is a noncontact thermal method that uses an Nd:YAG (neodymium-doped yttrium aluminium garnet) laser to create hemostasis by generating heat and direct vessel coagulation. It is not as effective as coaptive coagulation, because it lacks the use of compression to create a tamponade effect. [6] An additional deterrent to its use is expense. Laser therapy has largely been replaced with other endoscopic hemostatic methods.
