Abstract

A number of fields require state of the art low noise laser systems. The report has been written to aid the development of a laser source with a sub-hertz linewidth. The report brings together the most recent work in the field of laser stabilisation, along with a description of the relevant basic principles. There are explanations of the parameters used to describe laser noise and stability (power spectral density, Allan vari-ance, linewidth, modulation index). The effects of perturbation on a laser (plus reference cavity) system are discussed, including vibration, acoustic noise, thermal effects and opto-electrical considerations. The report concludes with a recommended laser system, drawing on the facts learnt during the process of writing this report.
