What does “stimulated emission of radiation” mean?
Radioactive particles in a laser emit gamma rays of the same wavelength.
Gas particles in a laser emit coherent light when bombarded with X-rays.
Gas particles in a laser emit photons of light when exposed to an electric current.
Electromagnetic currents are produced by neon particles when they bump into helium particles.

Gas particles in a laser emit photons of light when exposed to an electric current. This process is known as stimulated emission of radiation, as the electric current stimulates the emission of photons, which are then amplified and emitted in a coherent beam of light.
