If you are serious about quantum optics, this book is not just a reference—it is a rite of passage. Work through the chapters, derive every equation, and attempt the problems. You will emerge with a mastery of the subject that few other texts can provide.
Loudon provides a rigorous quantum mechanical description of optical detectors. He explains that a detector operates by absorbing a photon, meaning that optical interference must be understood as the interference of a photon with itself, rather than classical waves smashing together. This section lays the groundwork for understanding the famous Young's double-slit experiment at the single-photon level. 4. Non-Classical Light and Squeezing loudon quantum theory of light pdf
Platforms like Internet Archive or Google Books sometimes offer legal lending options or extensive previews.
If you're interested in downloading the Loudon quantum theory of light PDF, you can find it on various online platforms, including:
This describes light from traditional sources like lightbulbs or stars.
Even if you aren't a student, Loudon’s book serves as an incredible desk reference. The derivations are rigorous but accessible. It doesn't skip the "hard parts" just to be brief; it walks you through the commutation relations and field operators that define modern physics.

Physical and legitimate e-book editions (such as Kindle formats via Oxford Science Publications) are widely available through major booksellers.
It remains a standard university reference globally. Core Topics Covered in the Book
Beyond pure theory, Loudon’s insights laid the groundwork for the "Second Quantum Revolution." His treatment of squeezed states and non-classical light is fundamental to today’s developments in:
Most universities provide free access to the digital version of the third edition via Oxford University Press or digital libraries like Oxford Scholarship Online. Quick Facts: The Quantum Nature of Light Description
Perhaps its most profound legacy lies in the field of . The book's 1973 treatment of this notoriously difficult topic played a pivotal role in inspiring researchers Pegg and Barnett , who in the late 1980s developed a rigorous quantum phase formalism that resolved long-standing problems. This work effectively built upon Loudon's foundation to create a complete quantum description of optical phase.
While written decades ago, Loudon's derivations form the backbone of modern quantum technologies. Anyone working in the following fields will find his insights invaluable:
Understanding photon statistics is vital for secure key distribution.
The book begins with a review of classical electromagnetic theory. Loudon introduces the need for quantization by analyzing blackbody radiation and the photoelectric effect. He then demonstrates how to treat the electromagnetic field as a collection of independent harmonic oscillators. 2. Photon Statistics and Coherence
