Principle, Construction, and Working of He- Ne Gas LASER

The He -Ne Gas Laser was the first continuous laser. It was invented by Javan, Bennett and Harriot in 1961. The laser has 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 full 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.
