Question

Quizplus · Accepted Answer

The laser head contains the medium (such as gas or crystal) and the mirrors which are necessary for the laser to work. The cooling system is used to keep the medium at the appropriate temperature, and the excitation source (such as a flash lamp or electrical current) is used to energize the atoms or molecules in the medium. The delivery system is used to direct the laser beam to its target.
