An He-Ne laser works by exciting Neon atoms in the gas. The 632.8 nm optical light emitted by the laser is generated in the process when the Neon atoms decay from an excited state to an ordinary … WebA laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light. That extra energy “excites” the electrons enough to move from a lower-energy orbit to a higher-energy orbit around the atom’s nucleus.
