SUMMARY
The discussion centers on the differing descriptions of the ray transfer matrix of an interface as presented in two textbooks: "Lasers" by A.E. Siegman and "Laser Resonators and Beam Propagation" by N. Hodgson. The primary distinction lies in the use of the paraxial approximation and ray notation, specifically the (y, nu) form for rays in Siegman's work. The confusion arises from the interpretation of the optical path, which may lead to variations in the ray transfer matrix representations. Understanding these differences is crucial for accurate application in optical systems.
