Conference paper


Motivated by the recent experiments of Machida et al.,1 we shall consider two models for a laser with regular pump excitation. Machida et al. have demonstrated that the intensity fluctuations in the output light may be reduced below the shot noise limit if the pump fluctuations are suppressed. There have been a number of theoretical papers which have analysed the effect of reduced pump fluctuations on both lasers and masers.2–7
