Question

Explain the working of he - NE laser?​

Answer 1

Answer:

In the He-Ne laser the light is produced by atomic transitions within the Neon atom. ... Now when the Helium atoms move within the laser tube, they collide with the Neon atoms. At each collision some of the energy within the helium atom is transferred to the Neon atom and so raising it to an excited meta-stable state.
