Laser safety depends on precise knowledge of the physics of each laser and tissue effects in a constantly changing environment. The minimum requirement for certification in laser usage at any hospital should include a 'hands-on' course that includes basics in laser physics and usage of the laser in an animal laboratory. This usually means at least 5 hours of didactics and 5 hours of laboratory and observation of a few clinical cases performed by a trained physician. It is best to precept for some time, as understanding and using lasers depend on the amount of usage and quality of supervision. In this article focusing on laser safety, the most common lasers used in surgery and medicine are used to illustrate safety principles: the CO2, Nd:YAG, and argon lasers.
