WebWhat is a He-Ne Laser: A HeNe laser (also helium-neon laser or he-ne laser) is a type of continuously operating, or continuous-wave (CW) gas laser that uses a mixture of helium and neon gases as the active medium, most commonly emitting light at 632.8 nanometers (red). A gas laser light source produces a laser beam by applying a high voltage ... 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.
