Abstract

The choice of single mode semiconductor diode lasers for the source in fiber optic interferometers is primarily determined by the size, power requirements and potential cost of these devices. In interferometer systems (both bulk and fiber) powered by GaAlAs diode lasers, the noise properties of the laser primarily govern the noise properties of the interferometer. Since 1980 there has been a continuing interest in the low frequency properties of these devices. In this paper, the noise properties of the radiation emitted by these devices will be reviewed. Methods of improving the noise properties of these devices will be discussed. Properties of broadband sources suitable Sagnac interferometry will also be briefly discussed.
