Abstract

The spectral density of frequency noise is one of the most useful measures of laser temporal coherence and frequency stability. Like other measures of noise density, spectral density is a measure of the mean square fluctuation (in this case with units of Hz2) in a 1-Hz bandwidth as a function of frequency. The spectral density of frequency noise power therefore has units of Hz2/Hz, and the linear spectral density has units of hz/hz. as applied to laser frequency stabilization, the spectral density of frequency noise is necessary when calculating the loop gain and bandwidth required to achieve a given level of closed loop performance.1 The magnitude of the spectral density of frequency noise power is one of the main factors limiting the performance of gravity wave interferometers and coherent communications receivers; its measurement is of fundamental concern.2,3
