“Zur Quantentheorie der Strahlung.” In Physikalische Zeitschrift, XVIII, pp. 121-128

Leipzig: S. Hirzel, 1917. FIRST EDITION. Contemporary half cloth and marbled boards, preserved in a morocco slipcase. An excellent clean copy. First edition of this classic work on the quantum theory of radiation by Einstein in which he predicts the existence of the phenomenon of stimulated emission of radiation. He here analyzes the properties of photons and demonsrtrtes that Planck’s law is directly deducible from quantum theory and the concept of transition probabilities. Four decades later MASER and LASER devices are operated to prove him right.
