Abstract
In early research on Nd:glass amplifiers, it was discovered that scaling performance to larger diameters was often invalid; in some cases the expected values of certain parameters were not even approached. That experience demonstrated that there are certain limits to the size of large-aperture amplifiers, determined primarily by the complementary effects of amplified spontaneous emission (ASE) and parasitic oscillations (PO). These effects result in less energy storage or gain/cm, for example, when an amplifier is scaled up to a larger diameter. The diameter and gain of a stage are important in determining the X-factor or ultimate power capability for short pulses as we will investigate in Chap.7. When X-factor analysis, including both ASE and PO, is combined with cost, optimized system designs may be arrived at (Chap.8).
