The book begins by reviewing classical electromagnetic theory. It highlights where classical physics fails to explain specific phenomena, such as blackbody radiation and the photoelectric effect. This sets the stage for the necessity of quantization. 2. Quantization of the Radiation Field
: Using time-dependent quantum mechanics to explain how light interacts with matter.
The quantum theory of light, also known as the photon theory, was first proposed by Albert Einstein in 1905. However, it was Rodney Loudon who made significant contributions to the field in the 1960s. Loudon's work focused on the quantum electrodynamics (QED) of light, which describes the interactions between light and matter.

How we actually measure light and the statistical nature of photons.
: The historical and mathematical foundation of energy quantization in blackbody radiation.
For over half a century, Rodney Loudon’s The Quantum Theory of Light has been the definitive introduction to the field of quantum optics. First published in 1973, this renowned textbook has educated generations of physicists, guiding them from the fundamental principles of light-matter interaction to the cutting-edge experiments that define modern quantum technology. This article explores the book's legacy, its acclaimed author, and its comprehensive content, and provides a link to the official third edition.
coefficients through a quantum lens and dives deep into the Jaynes-Cummings model. This model describes a two-level atom interacting with a single quantized mode of light, serving as the bedrock for modern cavity quantum electrodynamics (QED).
