Spontaneous emission adds noise to the signal in laser amplifiers. In this paper the radiation characteristics of this noise and structures to reduce it are discussed. The structures make use of the spatial directionality of coherent light, and consist of aperture stops in combination with lenses. Their ultimate performance is studied. Signal-beam configurations necessary for optimum signal-to-noise (SNR) are described.
