Laser Marking Systems for Manufacturing: Abilities, Applications & More

Laser Marked Component

What do DVD players, checkout lines at the grocery store, and industrial marking machines all have in common? Lasers.

But not all lasers are the same. 

L.A.S.E.R. stands for Light Amplification by Stimulated Emission of Radiation. In simpler terms, it’s a highly concentrated beam of light. Lasers consist of a: 

  • Gain medium: a material that works in tandem with electrical currents to stimulate the photons of light as it passes through
  • Energy supply: Energy supply for lasers usually comes in the form of electrical currents. These currents are “pumped” through the grain medium to stimulate the atom as light passes through. The pumping of electrical currents causes the light to bounce faster through the grain medium. 
  • A material to provide optical feedback: The materials chosen for optical feedback have one primary job: steering. the way the beam of light is directed
