A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term “laser” originated as an acronym for “light amplification by stimulated emission of radiation”.

Although frequenlty used in surgery, it is essential that the patient is protected with laser resistant surgical drapes.
