Use of a Laser Diode as a Source in a Bragg Cell Spectrum Analyser

Abstract

The effects of using a solid state laser diode as the light source in an acousto-optic spectrum analyser are considered. Concentration is on high resolution analysers for use at communications frequencies. Recent developments in laser diode fabrication are summarised; key characteristics limiting performance are the spectral and spatial characteristics of the laser beam. The effects on analyser resolution and dynamic range are modelled and techniques proposed to improve performance.
