Abstract : The report discusses the problem of intrinsic internal modulation of a laser - modulation by altering the state of the active laser medium. Controlled modulation for information transmission and uncontrolled noise-producing modulations are considered. To demonstrate a correspondence-principle derivation of the classical laser equations of Lamb, it is shown that the lifetime distortions previously reported must be included in a quantum treatment. The problem of sound waves and time-dependent Zeeman-effect modulation is discussed. (Author)
