Maser Noise Considerations

J. Weber

The contribution of the saturation field to the noise figure of a three-level maser is calculated. It is shown that the effect is very small, under ordinary circumstances.Certain aspects of spontaneous-emission noise are considered. It is shown that the spontaneous-emission equivalent temperature for a free-electron vacuum-tube amplifier is one-half that of a maser.The possibility of eliminating spontaneous-emission noise is considered and it is concluded that more general quantum-mechanical amplifiers can in principle be constructed which will not have spontaneous-emission noise.

The quantum mechanics of signals and noise in attenuators and maser amplifiers

F.N.H. Robinson

Abstract A method used by Gordon, Walker & Louisell (1963) to treat the temporal behaviour of signals and noise is applied to obtain their spatial or steady-state behaviour in a lossy line or attenuator and a maser amplifier. The results relate the expectation values of the output voltage and its power spectrum to a classical signal input and the thermal state of the system. They differ in principle but not in practice from the results obtained by classical arguments.
