Conference paper


The development of high gain gas laser amplifiers[1] has renewed interest in the problem of non-linear amplification of broadband noise. Such signals may be externally applied or intrinsic to the amplifying medium itself, i.e, amplified spontaneous emission. In the linear regime, where the population inversion of the atomic medium is unsaturated, it is well-known that the amplified noise is spectrally narrowed; much less is known about the behavior of the field in the non-linear regime. In previous work either a random phase approximation of the field has been evoked to make the problem tractable analytically [2],[3],[4], or the possibility of phase coupling has been included in time domain computer analysis [5].
