Construction and operation. The gain medium of the laser, as suggested by its name, is a mixture of helium andneon gases, in approximately a 10:1 ratio, contained at low pressure in a glass envelope. ... The excited heliumatoms collide with neon atoms, exciting some of them to the state that radiates 632.8 nm.

It stands for helium neon laser. Its role is to is to increase the efficiency of the Lasing process.
Now,lets come to its working-
The mechanism producing light amplification and population inversion originates with the collision of energetic electrons with the helium atoms in the gas mixture.
