In a helium-neon laser, electrodes transfer electrical energy to the helium-neon gas mixture.
The first helium-neon laser was constructed in 1960 by Ali Javan, a physicist at the Massachusetts Institute of Technology (MIT).
Although the most common colour of light emitted by a helium-neon laser is red, there are also helium-neon lasers that emit green light and even some that emit invisible infrared light.
