He-Ne gas Laser: Its Principle, Construction and Working 

The Helium-Neon laser was the first continuous laser. It was invented by Javan, Bennett and Harroit in 1961. Laser have three components Laser medium: it is in the form of He-Ne gas mixture Pumping process:

The inelastic atom-atom collision Resonator cavity: it is made of a fully reflector and a partially reflecting plates parallel with high accuracy He-Ne gas laser is the four energy levels in which first He atoms are excited to bring the Ne atoms in required excited state by the atom-atom inelastic collision pumping process, the population inversion is achieved between the metastable and ground states.
