If a light signal is passed into the resonant cavity of an actively oscillating injection laser, an electrical signal at the difference frequency between laser and signal flows through the wire supplying the dc bias to the laser. Optical self-heterodyne detection with a laser oscillator was first described elsewhere. In this paper the authors present a small-signal analysis of heterodyne detection with a laser oscillator that is based solely on rate equations and introduces the externally applied signal as a course term into the photon rate equation. Since neither Maxwell's equations nor the wave equation are involved, this analysis is deemed simpler and more transparent than that reported earlier. Gain saturation of the active medium of the laser, which is responsible for broadening of the relaxation resonance, is taken into account.
