Abstract
The intensity noise of a laser is an important factor which must be considered in optical communication uses. In erbiuni-doped fiber lasers, one expects a relaxation oscillation frequency of the order of 10 kHz due to the relatively long fluorescence lifetime of erbium (~10 ms). Beyond this frequency, fluctuations in pump power are strongly damped, and the intensity noise power should, therefore, be dominated by spontaneous emission.
