TL;DR: In this paper, the effect of nonuniform saturation of the laser medium on the wavefront of a beam propagating through a laser amplifier is considered, and a number of examples of wavefront distortion are included.
Abstract: The effect of refractive index changes, caused by nonuniform saturation of the laser medium, on the wavefront of a beam propagating through a laser amplifier is considered. A number of examples of wavefront distortion are included. The effect of saturation-induced phase distortions on beam divergence and frequency modulation is discussed.

TL;DR: The advantages and disadvantages of single and double mirror systems are considered, and the image aberrations for present and future diameter ranges are discussed in relation to wave optical limits.
Abstract: Single and double mirror systems geometrical optical image aberrations noting focal number, angle of field, secondary magnification and mutual position tolerances
