Laser amplification is a process that increases the power of a laser beam by stimulating the emission of additional photons within an amplifying medium. This is achieved through a mechanism called stimulated emission, where incoming photons induce the emission of more photons with the same phase, frequency, and direction, resulting in an intensified laser output.

Stimulated emission is a process where an incoming photon induces an excited electron to drop to a lower energy level, emitting a second photon with the same phase, frequency, polarization, and direction as the incoming photon. This principle is fundamental to the operation of lasers, where it leads to the amplification of light.
