WebThe word “laser” is an acronym for “light amplification by stimulated emission of radiation.”. This name tells us a lot about how lasers work: light radiation is produced by stimulated emission and then amplified. Lasers are made of three main components: The active medium. The energy source. The resonant cavity.
