The basic principles for the development of laser, an acronym for: light amplification by stimulated emission of radiation, can be traced back to the paper written by Einstein in 1916 when he considered interaction of radiation and matter. In this paper Einstein predicted the existence of stimulated emission and' calculated the probability of its occurence. However, at thermal equilibrium the probability of absorption is larger than stimulated emission therefore the net effect is that light ...
