Abstract
An amplifier performance model that predicts a device's amplifier performance given the device's oscillator performance as a function of reflectivity was developed. Excellent agreement between single pass model predictions and single pass experimental data was obtained. The model was used to predict amplifier performance as the gain length was scaled from 0.3 to 4 m for three different lasers. When the amplifier performance curve is plotted in terms of nondimensiona l powers font vs ftn, gain length dependent, device independent curves result. The nondimensional amplifier performance curve showed that, with a single pass amplifier, one 0.3-m oscillator may be able to drive three amplifiers and one 4-m oscillator might be able to drive eight amplifiers. These results, which are independent of device, are sensitive to the oscillator power vs reflectivity performance curve in the 0-20% reflectivity range.
