Antiphase dynamics in intracavity second harmonic generation

Summary form only given. In the recent years, antiphase dynamics has appeared as a new topic in the study of multimode lasers. In this set-up, the green light is generated both by frequency doubling and by sum frequency generation from two different longitudinal modes. The control parameter is, in principle, the pump parameter. Another important parameter to control the dynamics is the angle between the fast axes of the two crystals in the cavity. The equations describing these processes can be approximated by the rate equations.<
