缩短自由电子激光放大器饱和长度的研究
Study on Saturation Length in a Free-electron Laser Amplifier
摘要
Abstract
The cost of a free-electron laser ( FEL) can be substantially reduced by shortening the saturation length of the beam-wave interaction .In order to study the way of shortening the saturation length of the beam-wave interaction , the authors research the impact of the key parameters on the free electron laser amplifier to the saturation length of the beam -wave interaction by nonlinear nu-merical simulation method .Taking an infrared FEL amplifier as example , a range of ±10%variation around 3000 Gauss results in a saturation length shortening of 0.11 m from 5.92 m (less than 2%), but optimizing the wiggler period , the electron beam energy and the light wavelength shortens the saturation length to 4.35 m (about 26.5%).In the present paper, results show that the wiggler am-plitude has a slight influence on shortening the saturation length , whereas the proper matching of the wiggler period , the laser wave-length and the electron-beam energy is able to greatly shorten the saturation length and increase the saturation power .关键词
