We present experimental results and a model of Nd:glass disk amplifiers which are
used in inertial confinement fusion research. We first review our previous measurements on
pulsed xenon flashlamps. We then discuss out measurements on the enhancement of the
Nd fluorescence decay rate in laser disks by amplified spontaneous emission. Using these
data, we have constructed a model of flashlamp pumping which treats the transfer efficiency
of pump light from the flashlamps to the disks as an empirical function. We have found a
simple description of this cavity transfer function which provides an excellent fit to the
amplifier results for various pump pulselengths. We discuss the concept of the pump area
ratio for describing the flashlamp packing density and show that amplifier performance is
optimized for values of this parameter near unity. We finally present results for both a singlesegment
and a multisegment disk amplifier. We have used these devices to investigate new
amplifier designs for a large scale fusion driver.
