The main methods of analysis of laser resonators ???????????????????????????????????????????????? matrix method, integral equation method, geometrical-optical method, are described. Special attention is given to methods of constructing resonator circuits generating laser radiation with special properties - power, low divergence, stability, taking special features of the active medium and laser operating regime into account. A large number of examples are discussed. Это и многое другое вы найдете в книге Laser Resonators (Vladimir P Bykov, Oleg O Silichev)
