Abstract
A theoretical and experimental study has been undertaken of a frequency modulated (FM) external cavity diode laser (ECDL). Operation as an FM laser is achieved using an intracavity electrooptic phase modulating crystal driven at a frequency close to but not equal to the cavity longitudinal mode spacing. FM lasers have applications in optical metrology, spectroscopy, and laser cooling of atoms.1
