"THE QUANTUM THEORY OF THE LASER: Yesterday, today and tomorrow"

Dr. Marlan Scully
Texas A&M, Baylor, and Princeton Universities


The quantum theory of the laser (QTL) has a checkered history. The early works by Townes, Schwinger, etc. were useful but did not provide the photon statistics, laser linewidth, etc. The first such theory was published [1] in 1965 (at the first Physics of Quantum Electronics conference).

Presently, the connection of the QTL with phase transition physics [2, 3] and other aspects of quantum many body physics are of interest. For example, this work has lead to new insights into quantum statistical mechanics involving the entropy of the BEC ground state [4]. Another current topic of investigation which has points in common with the QTL, is radiation from atoms falling into a black hole [5].

In the future, Yang’s off-diagonal long-range order (ODLRO) will be explored in connection with the QTL [6]. Investigating threshold behavior in living systems [7] via the QTL is another promising field of study.
