The theory of stimulated emission by Albert Einstein in 1917：
Being traced back to the 1910s, the theory foundation of laser cutting technology came from the Stimulated emission theory proposed by Albert Einstein in his 1917 paper On the Quantum Theory of Radiation. Stimulated emission is the basic physical process of laser generation.
In stimulated emission, an atom that is already in an excited state absorbs a photon with energy equal to its transition energy, gets stimulated, and releases two photons with identical energy, frequency, phase, and polarization direction, which laid a solid and scientific foundation for laser cutting technology.
