Influence of slippage parameter on swept-gain amplifiers
Abstract
A transit-time broadened swept-gain laser amplifier is investigated theoretically. General values of the slippage parameter, which measures the relative values of the time of transit of the radiating sources across the device and the pulse width of the sources, are considered. The sources in this calculation are two-level atoms, but the result should be directly applicable to the free-electron laser (FEL). Both the linear and nonlinear operation are considered, and the results are in much better agreement with FEL experiment than are the corresponding FEL calculations. A formula is found which predicts maximum output power for all values of slippage parameter.
